SEBI Grade A (IT) Mock Test - 4 - Question 6

Which of these should be the FIFTH sentence after rearrangement?

Detailed Solution for SEBI Grade A (IT) Mock Test - 4 - Question 6

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.

SEBI Grade A (IT) Mock Test - 4 - Question 7

Find out the ratio of total number of pen to total number chair from all quality, if quantity of chair increased by 10%.

Detailed Solution for SEBI Grade A (IT) Mock Test - 4 - Question 7

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

SEBI Grade A (IT) Mock Test - 4 - Question 8

If person sells chair and pen of quality A at price of ₹ 300 and ₹20 and quality B at a price at a price of ₹ 450 and ₹ 30 . then calculate total price earn by person.

Detailed Solution for SEBI Grade A (IT) Mock Test - 4 - Question 8

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

SEBI Grade A (IT) Mock Test - 4 - Question 10

Which of the following is not Correct?

Detailed Solution for SEBI Grade A (IT) Mock Test - 4 - Question 10

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.

  • 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.
SEBI Grade A (IT) Mock Test - 4 - Question 16
Train A is twice as long as train B. Both of them cross a bridge of length 3 times as long as train A. Train A takes 45 seconds to cross the bridge while train B takes 30 seconds. If the trains are running in opposite directions then find the time taken by the trains to cross each other.
Detailed Solution for SEBI Grade A (IT) Mock Test - 4 - Question 16

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

SEBI Grade A (IT) Mock Test - 4 - Question 17

What will come in the place of question mark (?) in the given expression?

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

Detailed Solution for SEBI Grade A (IT) Mock Test - 4 - Question 17

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

SEBI Grade A (IT) Mock Test - 4 - Question 18
The monthly savings of M and N is in the ratio of 4 : 5. If savings of M is increased by 10% and savings of N is decreased by 15%, then the difference between the savings of M and N would be Rs. 750. Find the average of original savings of M and N.
Detailed Solution for SEBI Grade A (IT) Mock Test - 4 - Question 18

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

SEBI Grade A (IT) Mock Test - 4 - Question 19

The area of the square is 125/64th of the area of the rhombus. One of the diagonals of rhombus is 9 cm less than the side of square whose diagonal is 25√2 cm then find the other diagonal of the rhombus (in cm)?

Detailed Solution for SEBI Grade A (IT) Mock Test - 4 - Question 19

Given:

Area of the square = 125/64th 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 = 125/64th 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.

SEBI Grade A (IT) Mock Test - 4 - Question 22

In which of the following network topology, the movement of the network is interrupted from adding or removing a computer from network?

Detailed Solution for SEBI Grade A (IT) Mock Test - 4 - Question 22

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.

Detailed Solution for SEBI Grade A (IT) Mock Test - 4 - Question 23

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.

SEBI Grade A (IT) Mock Test - 4 - Question 25

You have an interface on a router with the IP address of 192.168.192.10/29. Including the router interface, how many hosts can have IP addresses on the LAN attached to the router interface?

Detailed Solution for SEBI Grade A (IT) Mock Test - 4 - Question 25

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.

Binary Search algorithm uses which of the following approach
Detailed Solution for SEBI Grade A (IT) Mock Test - 4 - Question 28

The correct option is Divide and Conquer way to search elements
