  • d)
    Transmission Control Process
  • e)
    None of these
Correct answer is option 'C'. Can you explain this answer?

Diya Choudhary answered
Transmission Control Protocol (TCP) is a connection-oriented protocol that is used in the Internet Protocol (IP) suite. It is responsible for establishing and maintaining reliable connections between applications that are communicating over the Internet.

TCP was designed to provide a reliable, end-to-end, byte-stream communication service over an unreliable IP network. It ensures that data is transmitted in the correct order, without errors, and with minimal delays.

TCP is used by a wide range of applications, including web browsers, email clients, file transfer programs, and many others.

Some key features of TCP include:

- Connection-oriented: TCP establishes a virtual connection between two endpoints before data is transmitted.
- Reliable: TCP ensures that data is transmitted without errors, and retransmits any lost or corrupted packets.
- Flow control: TCP uses a sliding window protocol to manage the flow of data between the sender and receiver.
- Congestion control: TCP monitors network congestion and adjusts the rate at which data is transmitted to avoid congestion.

Overall, TCP is a critical protocol in the Internet Protocol suite, providing reliable, efficient, and scalable communication between applications over the Internet.

_________ is the assembly language for an imaginary architecture.
  • a)
    Byte code
  • b)
    Machine code
  • c)
    Native code
  • d)
    Executable code
  • e)
    Smart code
Correct answer is option 'A'. Can you explain this answer?

Tanishq Shah answered
Assembly language is a low-level programming language that is specific to a particular computer architecture. It is often considered a bridge between machine code and high-level programming languages. In assembly language, instructions are written using mnemonic codes that are easier for humans to understand than the binary codes used in machine code.

The options given in the question are:

a) Byte code
b) Machine code
c) Native code
d) Executable code
e) Smart code

The correct answer is option A, Byte code. Here's why:

Explanation of the correct answer:
Assembly language is a low-level programming language that is specific to a particular computer architecture. It is designed to be easily translated into machine code, which is the binary code that the computer's processor can understand and execute. However, assembly language is still human-readable and easier to understand than machine code.

Byte code, on the other hand, is a different concept. It is a low-level representation of a program that is typically used by virtual machines. Byte code is often generated by compilers for high-level programming languages, such as Java or Python, and it is executed by a virtual machine rather than directly by the computer's processor.

While byte code is a form of low-level representation, it is not the same as assembly language. Assembly language is specific to a particular computer architecture, whereas byte code is designed to be platform-independent and executed by a virtual machine.

In summary, assembly language is the correct answer because it is the low-level programming language specific to a particular computer architecture. Byte code, while also a low-level representation, is not assembly language.

A bottle full of juice contains480 ml of mixture of pulp and water in the ratio of _____, respectively. If 160 ml of mixture is taken out and 40 ml of pulp and 24 ml of water is added into the remaining mixture then the ratio of pulp to water in the resultant mixture becomes _____.
The values given in which of the following options will fill the blanks in the same order to make the statement true:
I. 5:3, 5:4

    Only I
  • b)
    All I, II and III
  • c)
    Only III
  • d)
    Only II and III
  • e)
    Only II
Correct answer is option 'D'. Can you explain this answer?

Harsh Gupta answered
To solve this question, we need to find the initial ratio of pulp to water in the bottle and then calculate the ratio after the given operations.

Initial Ratio:
Let the ratio of pulp to water in the bottle be a:b. Therefore, the total volume of the mixture is (a+b).

According to the given information, the total volume of the mixture is 480 ml. So we have:
(a+b) = 480

Ratio after Operations:
After taking out 160 ml of the mixture, the remaining volume of the mixture is (480 - 160) = 320 ml.

Now, 40 ml of pulp and 24 ml of water is added to the remaining mixture, which means the new volume of the mixture is (320 + 40 + 24) = 384 ml.

The new ratio of pulp to water in the resultant mixture is (a+40) : (b+24).

Therefore, (a+40) : (b+24) = x:y (let's assume)

Now, we have two equations:
(a+b) = 480 -- (1)
(a+40) : (b+24) = x:y -- (2)

Solving these two equations, we can find the values of a, b, x, and y.

Let's solve these equations.

From equation (2), we can cross-multiply:
(a+40)y = (b+24)x

Expanding this equation, we get:
ay + 40y = bx + 24x

Rearranging the terms, we have:
ay - bx = 24x - 40y -- (3)

Now, let's solve equations (1) and (3) simultaneously.

Multiplying equation (1) by a, we get:
a^2 + ab = 480a -- (4)

Multiplying equation (3) by a, we get:
a^2y - bxy = 24ax - 40ay -- (5)

Substituting the value of (a^2 + ab) from equation (4) in equation (5), we have:
480a - bxy = 24ax - 40ay

Rearranging the terms, we get:
480a - 24ax = bxy - 40ay

Factoring out the variables, we have:
24a(20 - x) = ay(b - 40)

Now, if we assume that the values in option II are correct, i.e., a:b = 9:7 and x:y = 55:41, we can substitute these values in the equation.

Substituting a:b = 9:7 and x:y = 55:41, we have:
24(9)(20 - 55) = (9)y(b - 40)

Simplifying this equation, we get:
-24(9)(35) = -31(b - 40)

Solving for b, we have:
-7560 = -31b + 1240

Rearranging the terms, we get:
-31b = -8800

Dividing by -31, we find:
b = 284.516129

But we know that the ratio of a:b is a whole number, so the values given in option II do not satisfy the condition. Therefore, option II is incorrect.

Now, we need to check the values

The peripheral nodes are connected to a central node, which rebroadcasts all transmissions received from any peripheral node to all peripheral nodes on the network, including the originating node is known as ____.
  • a)
    Bus
  • b)
    Star
  • c)
    Mesh
  • d)
    Ring
  • e)
    None of these
Correct answer is option 'B'. Can you explain this answer?

Ashwini Chatterjee answered
Peripheral nodes connected to a central node
In networking, peripheral nodes refer to devices that are connected to a central node or hub. These peripheral nodes can include computers, printers, scanners, or any other device that needs to communicate within the network. The central node acts as a central point of communication for all the peripheral nodes.

Rebroadcasting transmissions to all peripheral nodes
In the given scenario, the central node rebroadcasts all transmissions received from any peripheral node to all other peripheral nodes on the network, including the originating node. This means that any message or data sent by a peripheral node is received by the central node and then forwarded to all other peripheral nodes, ensuring that all nodes are aware of the information.

Types of network topologies
Different network topologies are used to connect peripheral nodes to a central node. Some common types of network topologies include:

1. Bus topology: In a bus topology, all peripheral nodes are connected to a single communication line known as a bus. The central node, also known as a bus master, receives all transmissions from peripheral nodes and rebroadcasts them to all other nodes on the network.

2. Star topology: In a star topology, all peripheral nodes are connected directly to the central node, forming a star-like structure. The central node acts as a hub or switch, receiving and rebroadcasting transmissions to all other peripheral nodes.

3. Mesh topology: In a mesh topology, each peripheral node is connected to every other node on the network. This allows for multiple paths for data transmission and provides redundancy in case of node failure. However, this type of topology can be complex and expensive to implement.

4. Ring topology: In a ring topology, each peripheral node is connected to the next node in a circular manner, forming a ring. The central node receives transmissions from one peripheral node and forwards them to the next node until they reach the destination. This topology provides a continuous loop for data transmission.

The correct answer: Star topology
Based on the given description, the network topology that fits the scenario is a star topology. In a star topology, the peripheral nodes are connected to a central node, which rebroadcasts all transmissions received from any peripheral node to all other peripheral nodes on the network, including the originating node. This ensures that all nodes are kept up-to-date with the transmitted information.

Rahul Mehta answered
LCM and HCF of two numbers are 630 and 9 respectively
Let the second number = p
⇒ 63 x p = 630 x 9
⇒ p = 90
Second number = 90
Sum of the two numbers = 63 + 90 = 153
Quantity 1 = 153
Quantity 2:
HCF and LCM of two numbers are 13 and 273 respectively
Let the second number = q
⇒ 39 x q = 13 x 273
⇒ p = 91
Second number = 91
Sum of the two numbers = 39 + 91 = 130
Quantity 2 = 130
Quantity 1 > Quantity 2

    Rs.24000
  • d)
    Rs.28000
  • e)
    Rs.44000
Correct answer is option 'C'. Can you explain this answer?

Akshita Kaur answered
To solve this question, let's analyze the given information step by step:

1. The rate of laptop P is more than Q, which is more than S.
- P > Q > S

2. The rate of laptop R is more than laptop V but less than laptop U.
- R > V and R < />

3. P is the third costliest laptop.
- P is not the costliest (as there are at least two laptops which are more expensive than P)
- P is not the second costliest (as there is at least one laptop which is more expensive than P)
- Therefore, P is the third costliest laptop.

4. The rate of laptop S is not least.
- S is not the cheapest laptop.

5. The rate of the third lowest laptop is Rs.20000.
- There are at least three laptops with rates less than Rs.20000.
- Therefore, the rate of the third lowest laptop is Rs.20000.

6. The rate of laptop T is less than laptop Q.
- T < />

7. The rate of laptop V is less than at-most 3 laptops.
- V is less expensive than 3 laptops at most.

Now, let's use the given information to find the rates of the laptops:

Since P is the third costliest laptop, it cannot be the cheapest or the second cheapest. Therefore, the rate of P is not Rs.20000.

Since S is not the cheapest, and the rate of the third lowest laptop is Rs.20000, S cannot be the third lowest laptop. Therefore, the rate of S is not Rs.20000.

From the information that T < q="" and="" the="" rate="" of="" the="" third="" lowest="" laptop="" is="" rs.20000,="" we="" can="" infer="" that="" t="" is="" the="" second="" lowest="" laptop="" with="" a="" rate="" of="" />

Since V is less expensive than at-most 3 laptops, and T is the second lowest laptop, V must be the cheapest laptop. Therefore, the rate of V is Rs.20000.

Since the rate of V is twice that of Q, and V is Rs.20000, the rate of Q is Rs.10000.

Since T is 1/5th of V, and V is Rs.20000, the rate of T is Rs.4000.

The average cost of V and T can be calculated as (20000 + 4000) / 2 = Rs. 12000.

Therefore, the correct answer is not listed among the options provided.

Ankit Jain answered
Understanding the Quadratic Equations
To compare Quantity A and Quantity B, we need to analyze the roots of the two quadratic equations presented.
Quantity A: 10p² – 7p + 1 = 0
- The coefficients are:
- A = 10
- B = -7
- C = 1
- Using the quadratic formula, the roots can be calculated as:
- p = [ -B ± √(B² - 4AC) ] / 2A
- The discriminant (D) for Quantity A:
- D = B² - 4AC = (-7)² - 4(10)(1) = 49 - 40 = 9 (which is positive)
- Since D is positive, Quantity A has two distinct real roots.
Quantity B: 35q² – 12q + 1 = 0
- The coefficients are:
- A = 35
- B = -12
- C = 1
- Similarly, using the quadratic formula:
- q = [ -B ± √(B² - 4AC) ] / 2A
- The discriminant (D) for Quantity B:
- D = B² - 4AC = (-12)² - 4(35)(1) = 144 - 140 = 4 (also positive)
- Since D is positive, Quantity B also has two distinct real roots.
Comparison of Quantities
- Both quadratics are capable of yielding two distinct real roots.
- The roots of Quantity A are influenced by larger coefficients, leading to a greater range of possible values.
- Analyzing the coefficients shows that the spread in Quantity A (due to a larger A value) typically results in larger numerical roots compared to Quantity B.
Conclusion
Based on the analysis of both quantities, we find:
- Quantity A has a higher likelihood of yielding larger or equal roots compared to Quantity B due to its greater leading coefficient and positive discriminant.
Thus, the correct answer is:
Option A: Quantity A ≥ Quantity B

The ratio between the efficiency of pipe Q and R is 4:3 respectively. Pipe S alone can empty the completely filled tank in 30 hours. If all the pipes P, Q, R and S are opened, then the empty tank can be filled in 48 hours. The time taken by pipe Q alone to fill the entire tank is 1.5 times the time taken by pipe P alone to fill the entire tank. Find out the time taken by pipe P and R together to fill 30% of the tank. It is assumed that except pipe S all the pipes are filling pipes.

Correct answer is option 'B'. Can you explain this answer?

Kavya Saxena answered
Let’s assume the capacity of the tank is 480 units.
Pipe S alone can empty the completely filled tank in 30 hours.
Efficiency of pipe S = 480/30 = -16 units/hour (Here negative sign represents that the pipe is emptying the tank.)
If all the pipes P, Q, R and S are opened, then the empty tank can be filled in 48 hours.
Efficiencies of pipe P, Q, R and S together = 480/48 = 10
Efficiencies of pipe P, Q and R together = 10 - (-16) = 10 + 16 = 26 units/hour Eq.(i)
The ratio between the efficiency of pipe Q and R is 4 : 3 respectively. Eq.(ii)
The time taken by pipe Q alone to fill the entire tank is 1.5 times the time taken by pipe P alone to fill the entire tank.
So the ratio between the time taken by pipe P and Q alone to fill the tank is 2:3. As we know that time and efficiency are inversely proportional to each other. Hence the ratio between the efficiency of pipe P and Q will be 3:2 respectively. Eq.(iii)
From Eq.(ii) and Eq.(iii), the ratio between the efficiency of pipe P, Q and R is 6:4:3 respectively.
From Eq.(i), the total efficiency of pipe P, Q and R together is 26.
Efficiency of pipe Q = 26 of (4/13) = 8 units/hour
Efficiency of pipe P and R together = 26-8 = 18 units/hour
Time taken by pipe P and R together to fill 30% of the tank = (480/18) of 30%
= 8 hours
Hence, option b is the correct answer.

Analysis:
- E visits the pet clinic three days before the one who has Goat.
- No one visits the clinic between E and A, who visits after Tuesday.
- Only two persons visit the clinic between A and the one who has Cat.
- The person who has Dog visits the clinic neither on Monday nor on Saturday.
- As many persons visit the clinic before the one who has Dog as after F, who doesn’t have Duck.
- G visits immediately before the one who has Dog.
- As many persons visit the clinic before the one who has Cat as after C.
- As many persons visit the clinic between A and the one who has Pigeon as between F and B.
- Both G and C neither have Hen nor Parrot.
- A doesn’t have Hen.

Solution:
- From the given information, we can deduce the following sequence:
- Sunday: E
- Monday:
- Tuesday:
- Wednesday: A
- Thursday:
- Friday:
- Saturday:
- From the information given, we know that G visits immediately before the one who has Dog. So, G cannot visit on Saturday. Therefore, G visits on Friday and the person with Dog visits on Saturday.
- Since only two persons visit the clinic between A and the one who has Cat, the person with Cat must visit on Wednesday and A visits on Tuesday.
- From the information that E visits three days before the person with Goat, we can determine that the person with Goat visits on Sunday.
- Since A visits after Tuesday and before the person with Pigeon, A visits on Wednesday and the person with Pigeon visits on Thursday.
- The remaining pets (Hen, Parrot, and Duck) can be placed accordingly.
Therefore, A visits the pet clinic after two days of G.

Ashwini Chatterjee answered
Address Bus and Memory Types

The address bus is used to communicate memory addresses between the CPU and the memory subsystem. The address bus is a collection of wires that transmit the address of the memory location being accessed. The size of the address bus determines the maximum amount of memory that can be addressed.

There are several types of memory in a computer system, and each has different characteristics. Some of these memories are directly connected to the address bus, while others are not.

Main Memory and Address Bus

Main memory is the primary memory of a computer system. It is used to store data and instructions that are currently being processed by the CPU. The main memory is connected to the address bus, and the size of the main memory is limited by the size of the address bus.

Onboard Memory and Address Bus

Onboard memory is the memory that is built into a device, such as a graphics card or a sound card. Onboard memory is not directly connected to the address bus, and it is not limited by the size of the address bus.

Cache Memory and Address Bus

Cache memory is a type of memory that is used to improve the performance of a computer system. Cache memory is located between the CPU and the main memory, and it stores frequently accessed data and instructions. Cache memory is not directly connected to the address bus, and it is not limited by the size of the address bus.

Secondary Memory and Address Bus

Secondary memory is a type of memory that is used to store data and instructions that are not currently being processed by the CPU. Secondary memory includes hard disk drives, solid-state drives, and optical drives. Secondary memory is not directly connected to the address bus, and it is not limited by the size of the address bus.

Answer

Based on the above explanation, the correct answer is option 'A', which is secondary memory. Secondary memory is not directly connected to the address bus and is not limited by the size of the address bus.

There are sentences given below that should be rearranged to form a meaningful paragraph. You must read the sentences and choose the best options for the questions that respectively follow the given sentences.
A. That the GST collections exceeded Rs. 1.33 lakh crore despite the challenging pandemic situation in January suggests revenues were now ‘on a stable trajectory and the 2021-22 targets would be exceeded’, said M.S. Mani, partner at Deloitte India.
B. GST revenues hit a record figure of nearly Rs. 1.41 lakh crore in January, compared to which February’s collections, _________ transactions undertaken in January, have moderated by 5.65%.
C. “This high growth during February 2022 should also be seen in the context of partial lockdowns, weekend and night curfews and various restrictions that were put in place by various States due to the Omicron wave, which peaked around 20th January,” it explained in a statement.
D. However, disparities between the collection trends among the States is a concern.
E. Seeking to emphasise the significance of these collections, the Ministry pointed out that ‘being a 28-day month, February normally witnesses revenues lower than that in January’.
Q. Which of the following statements would be the third last after rearrangement?
  • a)
    C
  • b)
    D
  • c)
    E
  • d)
    B
  • e)
    A
Correct answer is option 'A'. Can you explain this answer?

Kabir Verma answered
Sentence B that starts pretty well by introducing the news that GST collections have improved should be the first sentence. Now E emphasises ‘these collections’ that is the ones mentioned in B so, BE forms an obvious link. This tells us that E should be the second sentence. We know that D must come last due to the usage of ‘However’. So, out of the choices given, only C fits well for the answer. So, option (a) is correct.

Here four cases are possible which are given below in Case(i), Case(ii), Case(iii) and Case(iv).
Case(i) F _ _ _ D
Case(ii) D _ _ _ F
Case(iii) F _ _ _ _ D
Case(iv) D _ _ _ _ F
Car F is immediately right of car C.
In Case(iii), C is not possible as per the above given condition. So this case is eliminated.
Car G is not parked to the right of car D. The distance between car F and car G is 49 cm.
In Case(iv), car G is not possible as per the above given condition. So this case is eliminated.
In Case(i), G is possible in two places which are given below in Case(i)(a) and Case(i)(b).
In Case(ii), the distance given between car F and car G is not possible. So this case is eliminated.
The distance between car E and car H is less than 63 cm.
The distance between car E and F is an even number.
The distance between car C and car E is not the multiple of three.
In Case(i)(b), the distance between car C and car E = 35 + 28 = 63. So 63 is the multiple of 3 which is not possible. Hence this case is eliminated.
In Case(i)(a), the distance between car C and car E = 56 + 49 + 42 + 35 = 182. 182 is not the multiple of 3. Hence the given condition is applicable here.
Therefore, we got the final arrangement which is given above.
One car is parked to the right of E.

Jyoti Menon answered

Explanation:

Given Information:
- Nine persons from J to R are sitting in three rows - Row-1, Row-2, and Row-3 in a theatre.
- Row-1 is the nearest to the screen, Row-2 is behind Row-1, and Row-3 is behind Row-2.
- There are two vacant seats in each row.

Analysis:
- M is sitting immediately behind R.
- L sits between two vacant seats.
- P and J are diagonally opposite to each other.
- O is sitting behind one of the vacant seats from Row-1.
- M and N are sitting in the same row but not adjacent to each other.
- In Row 2, the second seat from the left is vacant.
- Number of vacant seats between Q and L are the same as vacant seats between N and M.
- J is sitting two rows in front of N.
- K is behind the person who is third to the right of J.
- P is not sitting in Row-2.

Solution:
- From the given information, we can see that J and O are in the same row (as J is two rows in front of N and M is sitting immediately behind R).
- Therefore, the pair of persons that does not belong to the same row is J and O. Hence, the correct answer is option A, J and O.

Correct answer is option 'D'. Can you explain this answer?

Rhea Reddy answered
The ratio between the cost price of article P and R is 3:4 respectively.
Let’s assume the cost price of article P and R is 6y and 8y respectively.
The cost price of article Q is 12.5% more than the cost price of article R.
cost price of article Q = (9/8) of 8y = 9y
Article Q was marked 30% above its cost price and a 20% discount was given on it while selling.
MRP of article Q = 130% of 9y = 11.7y
SP of article Q = 11.7y of 80% = 9.36y
Discount on article Q = 11.7y - 9.36y = 2.34y Eq.(i)
The MRP of article P is Rs. 330 less than the MRP of article Q.
MRP of article P = (11.7y - 330)
The selling price of article P is Rs. 756 after giving a discount of 10% on MRP.
(11.7y - 330) of 90% = 756
(11.7y - 330) = 840
11.7y = 840 + 330 = 1170
y = 100
CP of article R = 8y = 800
Discount on article P = (11.7y - 330) - 756
1170-1086
= 84 Eq.(ii)
Average of the discount given on article P and Q together = Eq.(i) + Eq.(ii)/2
= (234 + 84)/2
= 318/2
= 159

  • d)
    Rs.38600
  • e)
    None of these
Correct answer is option 'D'. Can you explain this answer?

Ritika Choudhury answered
Let number of Keyboards sold in shop A is 2x, so the number of mouse’s sold in shop A is 3x.
3x - 2x = 40
Or, x = 40.
Number of Keyboards sold in shop A = 40*2 = 80
Number of mouse’s sold in shop A = 40*3 = 120.
Number of keyboards sold in shop B = 120/2 = 60.
Number of mouse’s sold in shop B = 60*2/3 = 40.
Number of mouse’s sold in shop C = 120*(100-8.33)/100 = 110
Number of keyboards sold in shop C = 110 – 20 = 90
Number of keyboards sold in shop D = 90*7/9 = 70.
Number of mouse’s sold in shop D = 110*9/11 = 90
Number of keyboards sold in shop E = 70*2 = 140
Number of mouse’s sold in shop E = 130*2 – 140 = 120
Total revenue = 320*70 + 180*90 = Rs. 38600

Harshitha Joshi answered
Protocol
Protocols follow a common set of rules and instructions to facilitate communication between different devices on a network. They ensure that data is transmitted accurately and efficiently.

Server, Terminal, and Host
- Servers, terminals, and hosts are devices that rely on protocols to communicate with each other.
- While they play important roles in network communication, they do not inherently follow a common set of rules and instructions like protocols do.
- Servers, terminals, and hosts act as endpoints in a network and rely on protocols to govern their interactions.

Common Set of Rules
- Protocols define the format, timing, sequencing, and error control of data transmission.
- They establish guidelines for how devices should connect, send, receive, and interpret data.
- Examples of protocols include TCP/IP, HTTP, FTP, and SMTP, each serving specific communication purposes.

Conclusion
In summary, while servers, terminals, and hosts are essential components of a network, protocols are the underlying mechanisms that ensure proper communication between these devices. By adhering to a common set of rules and instructions, protocols enable seamless data exchange and network operations.

Shraddha Chopra answered
Number Series Analysis:
To find the wrong number in the given number series, let's analyze the pattern and logic behind the series.

Pattern Analysis:
Upon closely examining the given series, we can observe the following pattern:

- The series starts with 40.
- Each subsequent number in the series is obtained by multiplying the previous number by 2 and then adding an incrementing value.
- The incrementing value increases by 4 with each new term.
- The incrementing value starts from 0 for the second term.
- The incrementing value for each subsequent term is obtained by adding 4 to the previous incrementing value.

Calculating the Series:
Let's calculate the series based on the pattern:

- The first term is 40.
- To calculate the second term, we multiply the first term (40) by 2 and add the incrementing value (0): 40 * 2 + 0 = 80 + 0 = 80.
- To calculate the third term, we multiply the second term (80) by 2 and add the incrementing value (4): 80 * 2 + 4 = 160 + 4 = 164.
- To calculate the fourth term, we multiply the third term (164) by 2 and add the incrementing value (8): 164 * 2 + 8 = 328 + 8 = 336.
- To calculate the fifth term, we multiply the fourth term (336) by 2 and add the incrementing value (12): 336 * 2 + 12 = 672 + 12 = 684.
- To calculate the sixth term, we multiply the fifth term (684) by 2 and add the incrementing value (16): 684 * 2 + 16 = 1368 + 16 = 1384.

Identifying the Wrong Number:
Based on the pattern and the calculated series, all the numbers except one follow the logic correctly. Let's compare the calculated series with the given series:

- Given series: 40, 56, 124, 264, 520, 920
- Calculated series: 40, 80, 164, 336, 684, 1384

The Wrong Number:
By comparing the given series with the calculated series, we can see that the third term in the given series (124) does not match with the calculated series (164). Therefore, the wrong number in the series is 124 (option C).

Conclusion:
The wrong number in the given series is 124. All other numbers in the series follow the pattern correctly, but the third term deviates from the logic.

Step 2: 33 = (64/2) - 1
Step 3: 34 = (33*2) + 1
Step 4: 53 = (34/2) - 1
Step 5: 105 = (53*2) + 1
Step 6: 263.5 = (105/2) - 1

From the pattern, we can observe that:
- In the odd-numbered steps, we multiply the previous number by 2 and add 1.
- In the even-numbered steps, we divide the previous number by 2 and subtract 1.

So the pattern followed in the given number series is:
Odd steps: Multiply by 2 and add 1.
Even steps: Divide by 2 and subtract 1.

Now let's apply the pattern to the given series:
Step 1: 64
Step 2: (64*2) + 1 = 129
Step 3: (129/2) - 1 = 64.5
Step 4: (64.5*2) + 1 = 130
Step 5: (130/2) - 1 = 64
Step 6: (64*2) + 1 = 129

As we can see, the number 34 in the given series does not follow the pattern. According to the pattern, the number in the third step should be (33*2) + 1 = 67, not 34.

Therefore, the wrong number in the given series is 34, which corresponds to option C.

Rahul Mehta answered
Five people are sitting between R and J which is second to the left of N.
Here four cases are possible as per the given condition which are given below in Case(i), Case(ii), Case(iii) and Case(iv).
Case(i) R _ _ _ _ _ J _ N(↑)
Case(ii) R _ _ _ N(↓) _ J
Case(iii) J _ N(↑) _ _ _ R
Case(iv) N(↓) _ J _ _ _ _ _ R
Q sits exactly between R and N.
Case(i) R _ _ _ Q _ J _ N(↑)
Case(ii) R _ Q _ N(↓) _ J
Case(iii) J _ N(↑) _ Q _ R
Case(iv) N(↓) _ J _ Q _ _ _ R
The number of people sitting between J and Q is the same as the number of people sitting between Q and T who is second to the right of K.
In Case(i) and Case(iv), after putting T, K is not possible as per the above given condition. So this case is eliminated.
Case(ii) K(↑) _ T _ R _ Q _ N(↓) _ J
Case(iii) J _ N(↑) _ Q _ R _ T _ K(↓)
K does not face the north direction.
In Case(ii), K faces the north direction which is not possible as per the above given condition. So this case is eliminated.
Case(iii) J _ N(↑) _ Q _ R _ T _ K(↓)
O is immediately left of T.
In Case(iii), T is possible in two places which are given below in Case(iii)(a) and Case(iii)(b).
Case(iii)(a) J _ N(↑) _ Q _ R O T(↑) _ K(↓)
Case(iii)(b) J _ N(↑) _ Q _ R _ T(↓) O K(↓)
More than three people are sitting between O and L.
In Case(iii)(b), L is possible in two places which are given below in Case(iii)(b)(1) and Case(iii)(b)(2).
Case(iii)(a) J L N(↑) _ Q _ R O T(↑) _ K(↓)
Case(iii)(b)(1) J _ N(↑) L Q _ R _ T(↓) O K(↓)
Case(iii)(b)(2) J L N(↑) _ Q _ R _ T(↓) O K(↓)
L who is second to the right of S. M and T are not immediate neighbours of each other.
In Case(iii)(b)(1), S is possible in two places which are given below in Case(iii)(b)(1)(i) and Case(iii)(b)(1)(ii).
Case(iii)(a) J L N(↑) S(↓) Q M R O T(↑) _ K(↓)

Case(iii)(b)(2) J L N(↑) S(↓) Q M R _ T(↓) O K(↓)
Not more than one person is sitting between M and P.
In Case(iii)(a) and Case(iii)(b)(1)(i), P is not possible as per the above given condition. So this case is eliminated.
Case(iii)(b)(1)(ii) J S(↑) N(↑) L Q M R P T(↓) O K(↓)
Case(iii)(b)(2) J L N(↑) S(↓) Q M R P T(↓) O K(↓)
The immediate neighbours of S face opposite directions to each other.
Case(iii)(b)(1)(ii) J(↓) S(↑) N(↑) L Q M R P T(↓) O K(↓)
Case(iii)(b)(2) J L N(↑) S(↓) Q(↓) M R P T(↓) O K(↓)
As per the information given in the instructions, not more than two immediate neighbours face the same direction.
Case(iii)(b)(1)(ii) J(↓) S(↑) N(↑) L(↓) Q M R P T(↓) O(↑) K(↓)
Case(iii)(b)(2) J L N(↑) S(↓) Q(↓) M(↑) R P T(↓) O(↑) K(↓)
The direction of O and J is the same.
In Case(iii)(b)(1)(ii), the above given condition is not applicable. So this case is eliminated.
Case(iii)(b)(2) J(↑) L N(↑) S(↓) Q(↓) M(↑) R P T(↓) O(↑) K(↓)
The immediate neighbours of R face opposite directions to each other.
After that only the direction of L and R are remaining which we can determine from the instruction given in the question.
J(↑) L(↓) N(↑) S(↓) Q(↓) M(↑) R(↑) P(↓) T(↓) O(↑) K(↓)
Therefore, we got the final arrangement which is given above.

Read the passage carefully and answer the questions given below:
An aging king woke up one day acutely aware of his own mortality. He had no son, and his was a culture where only a male heir could take his place.
He decided that he would adopt a son who then could take his place, but he insisted that such an adopted son must be extraordinary in every sense of the word. He considered each of his advisors and relatives in turn, but found them wanting.
So he launched a competition in his kingdom, open to all boys, no matter what their background. Ten boys made it to the very top. There was little to separate these boys in terms of intelligence and physical attributes and capabilities.
The king said to them, 'I have one last test and whoever comes top will become my adopted son and heir to my throne.' Then he said, 'This kingdom depends solely on agriculture, so the king must know how to cultivate plants. Here are seven seeds of grain for each of you. Take them home. Plant and nurture them for six weeks. At the end of six weeks, we shall see who has done the best job of cultivating the grain. That person will be my son and my heir. '
The boys took their seeds and hurried home. Each got a pot, prepared soil, and sowed his seeds. There was much excitement in the kingdom as the people waited to see who was destined to be their next king.
In one home, the boy and his parents were almost heartbroken when the days stretched into weeks and the seeds failed to sprout. The boy did not know what had gone wrong. He had selected the soil carefully, he had applied the right quantity and type of fertilizer, he had been very dutiful in watering it at the right intervals, he had even prayed over it day and night and yet his seeds had turned out to be unproductive.
Some of his friends advised him to go and buy seed from the market and plant that.'After all,' they said, 'how can anyone tell seeds of grain one from another?'
But his parents who had always taught him the value of integrity reminded him that if the king wanted them to plant just any grain, he would have asked them to go for their own seed. 'If you take anything different from what the king gave you that would be dishonest. Maybe we are not destined for the throne. If so, let it be, but don't be found to have deceived the king,' they told him.
The appointed day came and the boys returned to the palace each of them proudly exhibiting a pot of healthy seedlings. It was obvious that the other nine boys had had great success with their seeds. The king began making his way down the line of eager boys and asked each of them, 'Is this what came out of the seeds I gave you?' And each boy responded, 'Yes, your majesty.' And the king would nod and move down the line.
The king finally got to the last boy in the line-up. The boy was shaking. He feared that the king might have him thrown into prison for wasting his seeds. 'What did you do with the seeds I gave you?' the king asked.
‘I planted them and cared for them diligently, Your Majesty, but alas they failed to sprout,' the boy said. He hung his head in shame, and the crowd jeered. But the king raised his hands and signaled for silence. Then he said, 'My people behold your next king.'
The people were confused. 'Why that one?' many asked.’ How can he be the right choice?' The king took his place on his throne with the boy by his side and said, 'I gave these boys boiled seeds. This test was not for cultivating grain. It was a test of character; a test of integrity. It was the ultimate test. If a king must have one quality, it must be that he should be above dishonesty. Only this boy passed the test. A boiled seed cannot sprout.'
Q. Why did the king ask the boys to cultivate the seeds?
  • a)
    He wanted to test their resourcefulness when faced with a difficult test
  • b)
    He wanted to test their agricultural skills as the state’s economy was mostly agriculture based
  • c)
    He wanted to check if the contestants knew how to grow saplings from boiled seeds
  • d)
    He wanted to check if the contestants were good at following orders
  • e)
    None of these
Correct answer is option 'E'. Can you explain this answer?

Rhea Reddy answered
The King asked the boys to cultivate the seeds to check their honesty and integrity.

Rahul Mehta answered
As per given data in the passage
The total number of students is 2500
The respective ratio of girls to boys in the school is 3 : 2
The number of girls
⇒ 3/5 × 2500 = 1500
The number of boys
⇒2/5 × 2500 = 1000
The number of boys playing cricket only ⇒ 20% of the number of boys
⇒ 20/100 × 1000 = 200
The number of girls playing table-tennis, badminton and carom only:
⇒ 25% of the number of girls
The number of boys playing football only:
⇒ 26.8% of the number of boys
⇒ 26.8/100 × 1000 = 268
The number of girls playing cricket only:
⇒ 175/100 × 200 = 350
The number of boys playing hockey table-tennis and carom only:
⇒ 25.7/100 × 1000 = 257
The number of girls playing badminton only:
⇒ 14 × 1500 = 375
The respective ratio of girls to boys playing only chess is 12 : 11.
The number of girls playing chess only ⇒ 12/11 × 275 = 300
The number of girls playing football and hockey only
⇒ 1500 − (375 + 350 + 375 + 300)
⇒ 1500 − 1400 = 100
The number of boys plays chess only ⇒ 1000 − (200 + 268 + 257)
⇒ 1000 − 725= 275
The total number of students playing more than one game ⇒ 375 + 257 + 100 = 732
Now according to the question, it is clear that the number of students playing hockey
⇒ 257 + 100 = 357
Therefore, the percentage becomes:
⇒ Number of students playing Hockey/Total number of students×100
⇒ 357/2500 × 100 = 14.28%
