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

**Which is not the prime number?**.- 43
- 57
- 73
- 101

**Answer:****57****Explanation:**A positive natural number is called prime number if nothing divides it except the number itself and 1.

57 is not a prime number as it is divisible by 3 and 19 also, apart from 1 and 57.**If the average of four consecutive odd numbers is 12, find the smallest of these numbers?**- 5
- 7
- 9
- 11

**Answer:****9****Explanation:**Let the numbers be x, x+2, x+4 and x+6

Then (x + x + 2 + x + 4 + x + 6)/4 = 12

∴ 4x + 12 = 48

∴ x = 9**Two numbers are in the ratio of 2:9. If their H. C. F. is 19, numbers are:**- 6, 27
- 8, 36
- 38, 171
- 20, 90

**Answer:****38, 171****Explanation:**Let the numbers be 2X and 9X

Then their H.C.F. is X, so X = 19

∴ Numbers are (2×19 and 9×19) i.e. 38 and 171**HCF of two numbers is 11 and their LCM is 385. If the numbers do not differ by more than 50, what is the sum of the two numbers ?**- 132
- 35
- 12
- 36

**Answer:****132****Explanation:**Product of numbers = LCM x HCF

=> 4235 = 11 x 385Let the numbers be of the form 11m and 11n,

such that ‘m’ and ‘n’ are co-primes.

=> 11m x 11n = 4235

=> m x n = 35

=> (m, n) can be either of (1, 35), (35, 1), (5, 7), (7, 5).

=> The numbers can be (11, 385), (385, 11), (55, 77), (77, 55).But it is given that the numbers cannot differ by more than 50.

Hence, the numbers are 55 and 77.

Therefore, sum of the two numbers = 55 + 77 = 132**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.**- 40
- 44
- 64
- 80

**Answer:****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 unitHere, 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 unitSo, we have

20 x 18 x 8 / 1 = (20 + x) x 10 x 9 / 2

=> x + 20 = 64

=> x = 44Therefore, number of additional men employed = 44

**Two outlet pipes A and B are connected to a full tank. Pipe A alone can empty the tank in 10 minutes and pipe B alone can empty the tank in 30 minutes. If both are opened together, how much time will it take to empty the tank completely?**- 7 minutes
- 7 minutes 30 seconds
- 6 minutes
- 6 minutes 30 seconds

**Answer:****7 minutes 30 seconds****Explanation:**Let the capacity of the tank be LCM(10, 30) = 30 units.

=> Efficiency of pipe A = 30 / 10 = 3 units / minute

=> Efficiency of pipe A = 30 / 30 = 1 units / minute

=> Combined efficiency of pipe A and pipe B = 4 units / minuteTherefore, time required to empty the tank

if both pipes work = 30 / 4 = 7 minutes 30 seconds**Three pipes A, B and C are connected to a tank. Working alone, they require 10 hours, 20 hours and 30 hours respectively. After some time, A is closed and after another 2 hours, B is also closed. C works for another 14 hours so that the tank gets filled completely. Find the time (in hours) after which pipe A was closed.**- 1
- 1.5
- 2
- 3

**Answer:****2****Explanation:**Let the capacity of the tank be LCM (10, 20, 30) = 60

=> Efficiency of pipe A = 60 / 10 = 6 units / hour

=> Efficiency of pipe B = 60 / 20 = 3 units / hour

=> Efficiency of pipe C = 60 / 30 = 2 units / hourNow, all three work for some time, say ‘t’ hours.

So, B and C work for 2 more hours after ‘t’ hours

and then, C works for another 14 hours.=> Combined efficiency of pipe A, pipe B and pipe C = 11 units / hour

=> Combined efficiency of pipe B and pipe C = 5 units / hourSo, we have 11 x t + 5 x 2 + 14 x 2 = 60

=> 11 t + 10 + 28 = 60

=> 11 t = 60 – 38

=> 11 t = 22

=> t = 2Therefore, A was closed after 2 hours.

**Two cars with speed of 15 kmph and 30 kmph respectively are 100 km apart and face each other. The distance between them 5 minutes before crossing is**- 2.75
- 3.75
- 4.75
- 5.75

**Answer:****3.75****Explanation:**As the two cars are moving towards each other,

their relative speed will be = 15+30 = 45 kmph.The distance between them 5 minutes before crossing

will be equal to the distance travelled by their relative speed in 5 minutes,

i.e. Required distance = Relative speed (in km per min) * time (in minutes) = (45/60)*5 = 3.75 km.**If Geeta can give a start of 100 m of distance or 20 s of time to her friend Meena in a race of 1000 meters. How much time Geeta will take to cover the 1000 meters?**- 200 sec
- 160 sec
- 180 sec
- 140 sec

**Answer:****180 sec****Explanation:**That means Meena will cover 100 m in 20 sec

=> meena can cover 1000 m in = 200 secs

Geeta can give a start of 100 m or 20 sec to Meena

=> Geeta will take 20 sec less than Meena

=> Geeta will take 180 sec to cover 1000 meters.**A boatman takes 3 hours 45 minutes to travel 15 km downstream and takes 2 hours 30 minutes to travel 5 km upstream of a river. What is the speed of the stream of the river in km/h?**- 2 km/h
- 1 km/h
- 6 km/h
- 4 km/h

**Answer:****1 km/h****Explanation:**Downstream:

Time taken = 3 + 45/60 = 3 + 3/4 = 15/4 h.

Distance covered = 15 km.

Downstream Speed = 15 / (15/4) = 4 km/h.Upstream:

Time taken = 2 + 30/60 = 2 + 1/2 = 5/2 h.

Distance covered = 5 km.

Upstream Speed = 5 / (5/2) = 2 km/h.We know, speed of stream = 1/2 (Downstream Speed – Upstream Speed) = 1/2 (4-2) = 1 km/h.

### Logical Reasoning

**Find wrong number in series:**

2, 3, 6, 0, 8, -3, 14, -6- 3
- 0
- 8
- 3

**Answer:****C****Explanation:**Two alternate series:

2 + 4 = 6,

3 – 3 = 0

6 + 4 = 10,

0 – 3 = -3

10 + 4 = 14

-3 – 3 = -6- 9848 x 125 = ?
- 1232000
- 1242000
- 1231000
- 1233000

**Answer:****1231000****Explanation:**9848 x 125

= 9848 x 53

= 9848 x (10 / 2)^{3}

= 9848 x (10^{3}/ 2^{3})

= 9848 x (1000/8)

= 1231000**Directions to solve Question 3 and 4: Each of the questions given below consists of a statement and/or a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statement(s) is/are sufficient to answer the given question.**

Read both the statements and Give answer

(a) if the data in Statement I alone is sufficient to answer the question, while the data in Statement II alone is not sufficient to answer the question.

(b) if the data in Statement II alone is sufficient to answer the question, while the data in Statement I alone is not sufficient to answer the question.

(c) if the data in each Statement I and Statement II alone is sufficient to answer the question.

(d) if the data even in both Statements I and II together are not sufficient to answer the question.

(e) if the data in both Statements I and II together are necessary to answer the question. **Is x + y = 0?**

Statement I – x.y < 0

Statement II – x^{2}= y^{2}- (a)
- (b)
- (c)
- (d)
- (e)

**Answer:****(e) if the data in both Statements I and II together are necessary to answer the question.****Explanation:**For x + y = 0, there are 2 cases:

Case 1:

x and y are of opposite sign.

This can be inferred from x.y < 0 Case 2: x = y = 0 This can be inferred from x^{2}= y^{2}Hence the data in both Statements I and II together

are necessary to answer the question.**What is the probability that x**^{3}– 8 = 0 when x is selected from a set of 8 integers?
