# WIPRO Placement Paper 8 | Written Test

This is a WIPRO model placement paper for placement preparation. This placement paper will cover aptitude, logical and reasoning, verbal and coding questions that are asked in WIPRO recruitment drives and also strictly follows the pattern of questions asked in WIPRO interviews. It is recommended to solve each one of the following questions to increase your chances of clearing the WIPRO interview.

### Quantitative Analysis

1. What is the sum of two consecutive odd numbers, the difference of whose squares is 56?.
1. 30
2. 28
3. 34
4. 32

```
28
```

Explanation:

Let the no. be x and (x +2).
Then (x +2)2 – x2 = 56
4x + 4 = 56
x + 1 = 14
x = 13
Sum of numbers = x + (x +2) = 28

2. Express 252 as a product of primes.
1. 2 * 2 * 3 * 3 * 7
2. 3* 3 * 3 * 3 * 7
3. 2 * 2 * 2* 3 * 7
4. 2 * 3 * 3 * 3 * 7

```
2 * 2 * 3 * 3 * 7
```
3. Two numbers are in the ratio 3 : 5. If their L.C.M. is 75. what is sum of the numbers?
1. 25
2. 45
3. 40
4. 50

```
40
```

Explanation:

1st number = 3x
2nd number =5x
LCM of 3x and 5x is 15x
=> 15x = 75
=> x = 5
sum = 15+25 =40

4. A person employed a group of 20 men for a construction job. These 20 men working 8 hours a day can complete the job in 28 days. The work started on time but after 18 days, it was observed that two-thirds of the work was still pending. To avoid penalty and complete the work on time, the employer had to employ more men and also increase the working hours to 9 hours a day. Find the additional number of men employed if the efficiency of all men is the same.
1. 40
2. 44
3. 64
4. 80

```
44
```

Explanation:

Let the total work be 3 units and additional men employed after 18 days be ‘x’.
=> Work done in first 18 days by 20 men working 8 hours a day = (1/3) x 3 = 1 unit
=> Work done in last 10 days by (20 + x) men working 9 hours a day = (2/3) x 3 = 2 unit
Here, we need to apply the formula M1 D1 H1 E1 / W1 = M2 D2 H2 E2 / W2, where
M1 = 20 men
D1 = 18 days
H1 = 8 hours/day
W1 = 1 unit
E1 = E2 = Efficiency of each man
M2 = (20 + x) men
D2 = 10 days
H2 = 9 hours/day
W2 = 2 unit

So, we have
20 x 18 x 8 / 1 = (20 + x) x 10 x 9 / 2
=> x + 20 = 64
=> x = 44
Therefore, additional men employed = 44

5. Three pipes A, B and C were opened to fill a tank. Working alone, A, B and C require 10, 15 and 20 hours respectively. A was opened at 7 AM, B at 8 AM and C at 9 AM. At what time the tank would be completely filled, given that pipe C can only work for 3 hours at a stretch, and needs 1-hour standing time to work again.
1. 12 : 00 PM
2. 12 : 30 PM
3. 1 : 00 PM
4. 1 : 30 PM

```
12 : 30 PM
```

Explanation:

Let the capacity of the tank be LCM (10, 15, 20) = 60
=> Efficiency of pipe A = 60 / 10 = 6 units / hour
=> Efficiency of pipe B = 60 / 15 = 4 units / hour
=> Efficiency of pipe C = 60 / 20 = 3 units / hour
=> Combined efficiency of all three pipes = 13 units / hour

Till 9 AM, A works for 2 hours and B work for 1 hour.
=> Tank filled in 2 hours by A = 12 units
=> Tank filled in 1 hour by B = 4 units
=> Tank filled till 9 AM = 16 units
=> Tank still empty = 60 – 16 = 44 units

Now, all three pipes work for 3 hours with the efficiency of 13 units / hour.
=> Tank filled in 3 more hours = 39 units
=> Tank filled till 12 PM = 16 + 39 units = 55 units
=> Tank empty = 60 – 55 = 5 units

Now, C is closed for 1 hour and these remaining 5 units would be filled by A and B working together with the efficiency 10 units / hour.
=> Time taken to fill these remaining 5 units = 5 / 10 = 0.5 hours

Therefore, time at which the tank will be completely filled = 12 PM + 0.5 hours = 12 : 30 PM

6. Rajdhani Express halts for 3 minutes every time it covers a distance of 75 km. If the train runs at a speed of 100 km/h and the destination is 600 km away from the source, find out the time taken to reach the destination station from the source station.
1. 6 h 21 min
2. 6 h 22 min
3. 6 h 23 min
4. 6 h 24 min

```
6 h 21 min
```

Explanation:

Since the train runs at a speed of 100 km/h, the time taken to cover 600 km = 600/100 = 6 h.
Number of times the train halts = 600/75 – 1 = 7.
Since the train halts for 3 minutes at each stop, the time spent waiting = 7 * 3 = 21 min.
Therefore, total time taken = 6 h 21 min.

7. A train crosses a pole in 20 sec. If the length of train is 500 meters, what is the speed of the train?
1. 27 m/s
2. 20 m/s
3. 25 m/s
4. 30 m/s

```
25 m/s
```

Explanation:

V = 500/20 = 25 m/s

8. Felix spends 66.66% of his salary and saves Rs 1200 every month. Calculate his monthly expenditure in Rupees.
1. Rs 2402
2. Rs 2400
3. Rs 2401
4. Rs 2405

```
Rs 2400
```

Explanation:

Let Felix’s monthly salary be Rs x. Then,
(100 – 66.66)% of x = Rs 1200
=> 33.33 % of x = Rs 1200
=> x/3 = Rs 1200
=> x = Rs 3600.
Therefore, his monthly expenditure = 3600 – 1200 = Rs 2400.

9. Mark, Steve and Bill get their salaries in the ratio of 2:3:5. If their salaries are incremented by 15%, 10%, and 20% respectively, the new ratio of their salaries becomes:
1. 8:16:15
2. 23:33:60
3. 33:30:20
4. 21:25:32

```
23:33:60
```

Explanation:

Let their old salaries be 2a, 3a, 5a respectively.
Then, their new salaries become:
115% of 2a = 2a x 1.15 = 2.3a
110% of 3a = 3a x 1.10 = 3.3a
120% of 5a = 5a x 1.20 = 6a
So, the new ratio becomes
2.3a:3.3a:6a
Upon simplification, this becomes
23:33:60

10. The present ages of A, B and C are in proportions 4:5:9. Nine years ago, sum of their ages was 45 years. Find their present ages in years
1. 15, 20, 35
2. 20, 24, 36
3. 20, 25, 45
4. 16, 20, 36

```
16, 20, 36
```

Explanation:

Let the current ages of A, B and C be ax years, 5x years and 9x respectively.
Then (4x-9) + (5x-9) + (9x-9) =45
=> 18x – 27 = 45
=> 18x = 72
=> x = 4
Present ages of A, B and C are 4x = 16, 5x = 20, 9x = 36 respectively.
