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

**The product of two numbers is 108 and the sum of their squares is 225. The difference of the number is:**.

- 5
- 4
- 3
- None of these

**Answer:****57****Explanation:**Let the numbers be x and y.

Then xy = 108 and x^{2}+ y^{2}= 225

(x –y)^{2}= x^{2}+ y^{2}– 2xy

(x –y)^{2}= 225 – 216

(x –y)^{2}= 9

Therefore (x –y) = 3**Which of the following has the most number of divisors?**- 99
- 101
- 176
- 182

**Answer:****176****Explanation:**99 = 1 * 3 * 3 * 11

101 = 1 * 101

176 = 1 * 2 * 2 * 2 * 2 * 11

182 = 1 * 2 * 7 * 13

Clearly, 176 has the most number of divisors.**Ratio of two numbers is 3:2. If LCM of numbers is 60, then smaller number is?**- 20
- 30
- 40
- 50

**Answer:****20****Explanation:**say, 1st number =3x

2nd number =2x

LCM of numbers = 6x

given LCM = 60

=> x6 = 60

=>x = 10**6 men and 10 women were employed to make a road 360 km long. They were able to make 150 kilometres of road in 15 days by working 6 hours a day. After 15 days, two more men were employed and four women were removed. Also, the working hours were increased to 7 hours a day. If the daily working power of 2 men and 3 women are equal, find the total number of days required to complete the work.**- 19
- 35
- 34
- 50

**Answer:****34****Explanation:**We are given that the daily working power of 2 men and 3 women are equal.

=> 2 Em = 3 Ew

=> Em / Ew = 3/2, where ‘Em’ is the efficiency of 1 man and ‘Ew’ is the efficiency of 1 woman.

Therefore, the ratio of efficiency of man and woman = 3 : 2.

If ‘k’ is the constant of proportionality, Em = 3k and Ew = 2k.

Here, we need to apply the formula

**=> (M**, where_{i}E_{i}) D_{1}H_{1}/ W_{1}= (M_{j}E_{j}) D_{2}H_{2}/ W_{2}

=> (M_{i}E_{i}) = (6 x 3k) + (10 x 2k)

=> (M_{j}E_{j}) = (8 x 3k) + (6 x 2k)

D_{1}= 15 days

D_{2}= Number of days after increasing men and reducing women

H_{1}= 6 hours

H_{2}= 7 hours

W_{1}= 150 km

W_{2}= 210 kmSo, we have

38k x 15 x 6 / 150 = 36k x D_{2}x 7 / 210

=> 38k x 6 = 12k x D_{2}

=> D_{2}= 19 days

Therefore, total days required to complete the work = 15 + 19 = 34 days**Two pipes A and B can fill a tank in 10 hours and 30 hours respectively. Due to a leak in the tank, it takes 2.5 hours more to fill the tank. How much time would the leak alone will take to empty the tank ?**- 20 hours
- 25 hours
- 30 hours
- 35 hours

**Answer:****30 hours****Explanation:**Let the capacity of the tank be LCM (10, 30) = 30 units

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

=> Efficiency of pipe B = 30 / 30 = 1 units / hour

=> Combined efficiency of both pipes = 4 units / hour

Now, total time taken by A and B working together to fill the tank if there was no leak = 30 / 4 = 7.5 hours

=> Actual time taken = 7.5 + 2.5 = 10 hoursThe tank filled by A and B in these 2.5 hours is the extra work done to compensate the wastage by the leak in 10 hours.

=> 2.5 hours work of A and B together = 10 hours work of the leak

=> 2.5 x 4 = 10 x E, where ‘E’ is the efficiency of the leak.

=> E = 1 unit / hourTherefore, time taken by the leak alone to empty the full tank = 30 / 1 = 30 hours

**Max completes his journey at an average speed of 9 km/h. He covers the first 9 km at a speed of 6 km/h and he takes 1·5 hours to cover the remaining distance. Find out the speed at which he covered the remaining distance.**- 11 km/h
- 12 km/h
- 13 km/h
- 14 km/h

**Answer:****12 km/h****Explanation:**Let the required speed be x km/h.

Total time taken to finish his journey = (9/6 + 1·5) = 3 hours.

Total distance = 9 + 1·5x km.

Given, average speed = 9 km/h.

Therefore, (9 + 1·5x)/3 = 9

=> 9 + 1·5x = 27

=> 1·5x = 18

=> x = 12 km/h.**A train crosses a pole in 10 sec. If the length of train is 100 meters, what is the speed of the train in Kmph?**- 34
- 36
- 30
- 32

**Answer:****36****Explanation:**V = 100/10 = 10 m/s = 10*3600/1000 = 36Km/hr

**Jack and Robert appeared in an examination. Robert scored 9 marks less than Jack. Jack’s score was 56% of the sum of their scores added together. Calculate their individual scores.**- 22 and 33
- 41 and 35
- 40 and 35
- 42 and 33

**Answer:****42 and 33****Explanation:**Let Robert’s score be x. Then, Jack’s score = x+9.

Now, x+9 = 56% of [(x+9) + x]

=> x+9 = 14/25 × (2x + 9)

=> 25 × (x+9) = 14 × (2x+9)

=> 25x + 225 = 28x + 126

=> 3x = 99 => x = 33.

Therefore, Robert scored 33 marks and Jack scored 42 marks.**In a library, the ratio of the books on Computer, Physics and Mathematics is 5:7:8. If the collection of books is increased respectively by 40%, 50% and 75%, find out the new ratio:**- 3:9:5
- 7:5:3
- 2:3:4
- 2:5:4

**Answer:****2:3:4****Explanation:**40% increase will lead to a factor of 140 and similiarly 150 and 175

so the new ratio is

(5*140):(7*150):(8*175)

on solving we get 2:3:4

**A person’s present age is one-third of the age of his mother. After 12 years, his age will be one half of the age of his mother. What is the present age of his mother?**- 30
- 34
- 38
- 36

**Answer:****36****Explanation:**Let the present ages of son and his mother are x years and 3x years.

Then (3x + 12) = 2( x + 12)

=> 3x + 12 = 2x + 24

=> x = 12

=> Present age of mother = 3x = 36 years

### Verbal Reasoning

**A rewording of something written or spoken is a ______________**- paraphrase
- paradox
- paradigm
- paraffin

**Answer:****paraphrase****Explanation:**Paraphrase – To express something in different words so that it becomes easy for the listener to understand.

Paradox – A statement which sounds logical, but proves to be illogical when investigated.

Paradigm – A way of looking or thinking (perception) about something.

Paraffin – A flammable substance used in candles, polishes, etc.

So, A is the correct choice.

**Archimedes said, “Give me a lever long enough and a fulcrum on which to place it, and I will move the world.” The sentence above is an example of a ___________ statement.**- figurative
- collateral
- literal
- figurine

**Answer:****figurative****Explanation:**Here, we are talking about the figure of speech So, figurative is a figure of speech meaning:

Use of metamorphic meaning of words to explain your thoughts instead of literal use of them.**The man who is now Municipal Commissioner worked as ______________**- the security guard at a university
- a security guard at the university
- a security guard at university
- the security guard at the university

**Answer:****a security guard at the university****Explanation:**University considered as an organization that’s why article

**the**used before university.

And Post of security is a general post, so article**a**has been used for security guard.So, option (B) is true.

**Find the odd one in the following group of words.**mock, deride, praise, jeer

- mock
- deride
- praise
- jeer

**Answer:****praise****Explanation:****Meanings**

mock : tease

deride : poke/laugh at

praise : gratitude

jerk : foolSo except praise, all others are describing negative things.

In the present-day world, no individual or organization even think to

__plough a lonely furrow.__**The best meaning for the underlined phrase above is:**- work secretly
- remain aligned
- do without the help of others
- remain non-aligned

**Answer:****do without the help of others****Explanation:**Meaning of the phrase-: Follow a course of action in which one is isolated or in which one can act independently.

**I haven’t worked as a mechanic before, ________ I’ve been fixing cars since I was a child.**- always
- yet
- no longer
- already

**Answer:****yet****Explanation:****Always**is an adverb of frequency, like never, often, frequently, and usually.

**Yet**is a conjunction meaning nevertheless or however. Yet usually carries a sense of negation, so and yet means the same thing as but still.

**No longer**means not now as formerly; not any more.

We use**already**to show that something has happened sooner than it was expected to happen.Therefore, “yet” is the most appropriate choice here.

Option (B) is correct.**____________ is usually used for something that was done in the past and still applies (multiple events).**- Had/has/have been
- Was/were
- Had/was/were
- All of the above

**Answer:****Had/has/have been****Explanation:****Had/has/have been**is usually used for something that was done in the past and still applies (multiple events).**Was/were**usually applies to something done in the past that no longer applies (single event).So, option (A) is correct.
