The correct answer is RBI on behalf of GOI.

Key Points

• The given passage is about the Indian Financial System.
• Let us refer to the line from the passage, "Though one rupee notes and coins and small coins are issued by the Central Government, this distribution to the public is the sole responsibility of the RBI".
• From the given line we get to know even though one rupee and small coins are not issued by RBI, it is responsible for their distribution to the public.
• So, ​'RBI on behalf of GOI' is the correct option.

Mistake Points

• The government is responsible for conducting policies, actions, and affairs of (a state, organization, or people) with authority. So, options 2 and 3 are wrong.
• The Issue Department is a department under RBI that is responsible for the issue of currency in India. So, option 1 is also wrong.

The correct answer is Primary co-operative credit societies.

Key Points

• The given passage is about the Indian Financial System.
• Let us refer to the line from the passage, "Primary co-operative credit societies or banks were originally set up in villages to promote thrift and savings of the farmers and to meet their credit needs for cultivation".
• From the given line we get to know that to promote savings and careful usage of money among the farmers so that they can meet their credit needs for cultivation, many primary co-operative credit societies or banks were constructed.
• So, ​'Primary co-operative credit societies' is the correct option.

The correct answer is 'D.'

Key Points

• The correct sequence of the segments after rearrangement is AECBD.
  • The sentence 'A' is independent of any other sentence as it introduces the topic of ''The discovery of cosmic microwave background radiation.'' Hence, 'A' is the first part.
  • Sentence E will come after A as it is giving information about when and who discovered cosmic background radiation i.e. in 1964 by US physicist Arno Allan Penzias and radio-astronomer Robert Woodrow Wilson.
  • Sentence C will come after E as it gives further information about where and when cosmic background radiation was accepted or needed.
  • Sentence B will come after C as it is talking about a prior measurement of the cosmic background radiation (CMB) by Andrew McKellar in 1941.
  • The sentence 'D' is the concluding or final part as it concludes by saying that the significance of the measurement of the cosmic background radiation by Andrew McKellar was understood later after the Penzias and Wilson measurements.

Hence, the correct answer is option 3.

Paragraph after rearranging the sentences: The discovery of cosmic microwave background radiation constitutes a major development in modern physical cosmology. In 1964, US physicist Arno Allan Penzias and radio-astronomer Robert Woodrow Wilson discovered the CMB, estimating its temperature as 3.5 K, as they experimented with the Holmdel Horn Antenna. The new measurements were accepted as important evidence for a hot early Universe and as evidence against the rival steady-state theory as theoretical work around 1950 showed the need for a CMB for consistency with the simplest relativistic universe models. There had been a prior measurement of the cosmic background radiation (CMB) by Andrew McKellar in 1941 at an effective temperature of 2.3 K using CN stellar absorption lines observed by W. S. Adams. Although no reference to the CMB is made by McKellar, it was not until much later after the Penzias and Wilson measurements that the significance of this measurement was understood.

Total number of chair before increased = 450 + 1200 + 250 + 1000 = 2900

Total number of chair after increased = 2900 + 10% of 2900 = 2900 + 290 = 3190

Total number of pen = 850 + 950 + 550 + 1050 = 3400

∴ Required ratio = 3400 : 3190 = 340 : 319

Total money earn from quality A = 300 × 450 + 20 × 850 = 135000 + 17000 = 152000

Total money earn from quality B = 450 × 1200 + 30 × 550 = 540000 + 16500 = 556500

∴ Required Sum = 152000 + 556500 = 708500

1. The train with Wiring is delivered four days before the train H which is delivered two days after the train with Insulation.

2. The train | delivered immediately before the train with Insulation. The leave is planned on the day before the delivery of the train H and after the train I.

3. The train J, which is not delivered after leave, delivers immediately after the delivery of the train with Lumber which is not delivered after the train with Wiring. Hence, case 1 gets eliminated.

4. The train G delivers three days before the train K which is not delivered on the last day of the week. Hence, case 3 gets eliminated.

5. The train with Gravel is delivered immediately before the train with Glass. Hence, Case 3a gets eliminated.

Final arrangement

Given:

Ten boxes - P, Q, R, S, T, U, V, W, X and Y

Now,

1) Three boxes are placed between W and P.

2) Two boxes are placed between R and P.

The possibilities are -

3) Box W is not near to R and none of both boxes are either on the top or at the bottom. So Case I and Case III get eliminated as W is near to R in both cases. Also, there is one box above and below of W and R in Case II and Case IV.

The arrangement will be as follows -

4) Only one box is placed between box U and T where T is below U.

5) Box W was placed just above the box T. It means box U is placed just above box W.

6) Number of boxes below Q and above S is same.

7) Box X is not above box Q which is above box P. It means Box Q will be somewhere above Box P and therefore box S will be below Box P. Box X will be below box Q but we cannot determine its position right now.

The possibilities are -

8) More than two boxes are there between R and V. The only possible places for V in Case II (a) is Box 6, in Case II (b) is Box 6 and in Case IV is Box 5.

9) At least two boxes are between V and Y which is above R. Box Y should be above Box R and there should be a gap of more than two boxes between Box V and Box Y. This is not possible in Case II (a) so it gets eliminated. The remaining possibilities are -

Now, the possible places for X is Box 1 in Case II (b) and Box 8 in Case IV. But in Case IV, condition 7) is not satisfied as box X is placed above box Q which is not possible. So, the Case gets eliminated.

Thus, the final arrangement is -

Among the given options, all statements except ' Box below R is same as above the box Q' are correct.

Hence, the correct answer is Box below R is same as above the box Q.

The correct answer is emulation.

Key Points

• The blank gives the answer to the question word 'what'. hence we need a noun to fill this blank.
• Now let's understand the meaning of all options:
  • Copying: An instance of the making of a copy
  • Ape: Imitate uncritically and in every aspect
  • Simulation: The act of giving a false appearance
  • Emulation: Ambition to equal or excel
  • Multiplication: The act of producing offspring or multiplying by such production
• Hence, option 4 is the most appropriate answer.
  

Given:

We use the following symbols to denote the relation between parties:

1. The father-in-law of S, who is married to the son of U, has 2 grandchildren of the same gender.

2. X is the sister of R, who is the son of O.

3. R has 2 daughters.

4. Q is married to W.

5. T is the sister-in-law of P, who is married to V.

6. U is the mother of X.

7. Q is the father of S.

Combining all of them together, we get:

Hence, W is the Maternal Grandmother of T.

The correct answer is Gumption.

Key Points

• Gumption: quickness of perception; common sense.
  • The context says that the gumption of the man saved his life when threatened by the robber at the alley.
• Therefore, the correct answer is: The gumption of the man when he was threatened by the robber at the alley was the only reason his life was spared.

Additional Information​

The correct answer is Option 3.

Key Points

Only AE is the correct pair.

• Phrases B and C are grammatically incorrect.
• Since the verb in B is referring to 'times', which is a plural noun, 'was' is erroneous.
• The syntax of phrase C is incorrect. It should have been 'such monstrous was the storm'.

Thus we can see that B and C cannot make grammatically correct sentences, nor do they carry any contextual sense if they are joined with D, E or F.

The correct option is 4 i.e. A-D

Key Points

• Let's look at the given sentence in the following way
• We now ________ (A)ourselves upon a ________ (B), and began to ________ (C) into our personal ________ (D)
• property: a thing or things belonging to someone; possessions collectively.
• 'we now property ourselves' is contextually wrong.
• Instead, 'we now seated ourselves upon a rock' creates a meaning.
• 'personal property' is a correct phrase.
• Therefore, A and D should be interchanged.

• examine: inspect (someone or something) thoroughly in order to determine their nature or condition.
• Therefore, the correct sentence is, We now seated ourselves upon a rock and began to examine into our personal property.

Solution:

Given:

Time taken by train A = 45s.

Time taken by train B = 30s

Length of train A is twice that of train B.

Length of bridge is thrice that of train A.

Concept:

While crossing a bridge the total distance covered is the length of the train plus the length of the bridge.

While crossing each other the total distance covered is the summation of the lengths of the two trains.

Formula:

Speed = Distance/time.

Relative speed while going in opposite direction = sum of the speeds

Calculation:

Let the length of train B be x.

⇒ length of train A = 2x

⇒ length of bridge = 3 × 2x = 6x

Total distance covered while crossing the bridge

By train A is 2x + 6x = 8x

By train B is x + 6x = 7x

⇒ Speed of train A = 8x/45

⇒ Speed of train B = 7x/30

Total distance covered by the trains while crossing each other is x + 2x = 3x

Relative velocity while crossing each other is (8x/45) + (7x/30)

⇒ (8x/45) + (7x/30)

⇒ 37x/90

Time = (3x)/(37x/90)

⇒ Time = 7.29

∴ Time taken = 7.29 seconds

Concept used:

Follow the BODMAS rule to solve this question, as per the order given below

Calculations:

14 × 23 + ?2 + 10% of 1910 = 25% of 6148

⇒ 322 + ?² + (10/100) × 1910 = (25/100) × 6148

⇒ 322 + ?² + 191 = 1537

⇒ ?² = 1537 – 513

⇒ ?² = 1024

⇒ ? = √1024 = 32

∴ The value of ? is 32

Given:

Ratio of monthly savings of M and N is 4 : 5

Savings of M is increased by 10%

Savings of N is decreased by 15%

Difference between the savings of M and N would be Rs.750

Formula Used:

Average = (sum of all the observation)/(total number of observations)

Calculation:

Let savings of M and N be Rs. M and Rs. N respectively

According to the question,

⇒ M/N = 4/5

⇒ M = 4N/5

Now,

Savings of M is increased by 10% and savings of N is decreased by 15%

New Savings of M = M × 110/100

New Savings of N = N × 85/100

Now,

⇒ M × 110/100 – N × 85/100 = 750

⇒ 110 × 4N/5 – 85N = 75000

⇒ 88 N – 85N = 75000 × 5

⇒ 3N = Rs. 75000

⇒ N = Rs. 25000

⇒ M = 25000 × 4/5 = Rs. 20000

∴ Required average savings of M and N = (20000 + 25000)/2 = Rs.22500

Given:

Area of the square = 125/64^th of the area of the rhombus

One diagonal of rhombus = (side of square) – 9 cm

Diagonal of square = 25√2 cm

Formula Used:

Area of rhombus = 1/2 × d₁ × d₂

Area of square = (side × side)

Calculation:

Suppose the side of the square is x cm.

∴ Diagonal of square = x√2

⇒ x√2 = 25√2

⇒ x = 25 cm

One diagonal of the rhombus = (x – 9) cm

∴ One diagonal of the rhombus = (25 – 9) cm = 16 cm

Suppose the other diagonal of the rhombus is y cm.

Area of the rhombus = 1/2 × (16 × y) cm² = 8y

Area of the square = (25 × 25) = 625 cm²

According to question –

Area of the square = 125/64^th of the area of the rhombus

⇒ 625 = (125/64) × 8y

⇒ (625 × 64/125) = 8y

⇒ 320 = 8y

⇒ y = 320/8

⇒ y = 40 cm

∴ The another diagonal of the rhombus will be 40 cm.

• An IP Address uniquely identifies devices on a network.
• SSL (Secure Sockets Layer) is a cryptographic protocol designed to provide communications security over a computer network.
• A router is a hardware device that routes data from one network to another.
• HTTP (Hypertext Transfer Protocol) is the foundation of data communication for the World Wide Web.

The given answer is option 2.

Concept:

A regular expression (abbreviated regex or regexp; also known as a rational expression) is a string of characters that specifies a text search pattern. String-searching algorithms typically use such patterns for "find" or "find and replace" operations on strings, as well as input validation.

Hence the correct answer is Regex.

Additional Information

• A histogram is a graphical representation that divides a set of data points into user-defined ranges.
• Dict is an R package that implements a key-value dictionary data structure based on the R6 class. It is intended to be used in a manner similar to other languages' dictionary implementations (e.g. Python).
• Data Frames in R are R's generic data objects that are used to store tabular data.
• The r language is primarily used in statistics and data analytics to represent data graphically in software. R employs charts and graphs to graphically represent those data.

The correct answer is Ring

Key Points

• Ring Topology:
  • In a ring topology, each device is connected to exactly two other devices, forming a closed loop or ring.
  • Data travels in one direction through the ring.
  • It's relatively easy to install, but if one device or link in the ring fails, the entire network can be disrupted.
    

Additional Information

• Mesh Topology:
  • In a mesh topology, every device is connected to every other device in the network.
  • This provides multiple paths for communication between any pair of devices.
  • Offers high reliability and fault tolerance, as there are alternative routes if one link or node fails.
  • It's robust but can be complex and expensive to implement due to the numerous connections.
    
• Bus Topology:
  • In a bus topology, all devices share a common communication line or bus.
  • Communication travels in both directions but can only occur in one direction at a time.
  • It's simple and cost-effective but may face issues with congestion and reliability if the main bus fails.
    
• Star Topology:
  • In a star topology, all devices are connected to a central hub or switch.
  • The central hub manages and controls the communication flow.
  • It is easy to set up and maintain, but if the central hub fails, the entire network may be affected.
    

The correct answer is Last In First Out (LIFO).

Key Points

• A stack is a linear data structure that follows a particular order in which the operations are performed.
• The order may be LIFO (Last In First Out) or FILO (First In Last Out).
• In a LIFO structure, the most recently added item is the first to be removed.
• This is analogous to a stack of plates where you add a plate on top and also remove the topmost plate first.

Additional Information

• First In First Out (FIFO): This is a different type of data structure known as a queue. In FIFO, the first element added is the first one to be removed, similar to a line of people.

cp command copies the content of file1 into file2.

Six hosts are the maximum number of hosts on this LAN, including the router interface.

Key Points

• Although your router may provide up to 250 IP addresses, this does not imply that 100 devices can connect to the same wireless network at the same time.
• A router should have five different IP addresses and five different link-layer addresses.
• Each IP address belongs to the set of addresses assigned to a network.
• Each link-layer address also identifies the data-link layer connection's router.
• On an Android device, slide down from the top of the screen and hit "internet" to locate your router's IP address. Then, on the right, hit the gear button to select your WiFi network. Finally, beside Gateway, you'll notice your router's IP address if you scroll down.
• A message is broadcast to all hosts on a network using the 255 address. Just keep in mind that no one host can be assigned to the first and last addresses in any network or subnet. You should be able to assign IP addresses to 255 hosts at this point.

The correct answer is option 2.

Concept:

A data warehouse is a form of the data management system that is intended to facilitate and assist business intelligence (BI) and analytics operations. Data warehouses are designed mainly for querying and analysis, and they frequently store vast volumes of historical data.

• It refers to a business's electronic storage of a large amount of data that is intended for query and analysis rather than transaction processing.
• It is the process of converting data into information and making it available to consumers in a timely way so that it may be used to make a difference.
• A data warehouse is a centralized collection of data that can be studied to help people make better decisions.
• Data flows into a data warehouse on a regular basis from transactional systems, relational databases, and other sources. Business analysts, data engineers, data scientists, and decision-makers use BI tools, SQL clients, and other analytics software to access the data.

The following components are commonly found in a data warehouse:

• A relational database to store and manage data.
• In the data warehouse, ELT stands for extraction, loading, and transformation, and it is used to prepare data for analysis.
• Visualizing and presenting data to business users with client analysis tools.

Hence the correct answer is Storing a large volume of data.

The correct answer is It uses diamond-shaped symbols for the detection of restricted stories.

Key Points

• The correct interpretation for the usage of diamond-shaped symbols in flowcharts is for decision-making or branching, not for the detection of restricted stories.
• Diamonds are typically used to represent decision points that lead to different paths in the flow based on yes/no questions or true/false conditions.

The correct option is Divide and Conquer way to search elements

CONCEPT:

Binary search follows the divide and conquer technique.

To search for an element, first, find the middle element, if a match is found, then return the location.

Or, if the element is less than the middle element search will proceed in the left half, else the search will proceed into the right half.

Example:

List = [7, 12, 27, 30, 43] with index range from 0 to 4. and Key to search = 12

Thus the above searching takes 2 iterations for binary search to search key 12.

The correct answer is int array[10];.

Key Points

• In C++, to declare an array of 10 integers, you use the syntax int array[10];. This creates an array named array with 10 elements, each of type int.
• Arrays in C++ are fixed-size sequences of elements of the same type. The size of the array must be specified at the time of declaration.
• Each element in the array can be accessed using its index, which ranges from 0 to the size of the array minus one.

The correct option is 5 i.e., All of the above.

• Citrix was hit by hackers that potentially exposed large amounts of customer data.
• The WannaCry ransomware attack was made in May 2017 worldwide.
