Quantitative Analysis

Find the greatest number that will divide 355, 54 and 103 so as to leave the same remainder in each case.
1. 4
2. 7
3. 9
4. 13
```
 7 
```
Explanation:

Required number = H.C.F. of |a -b|, |b – c| and |c – a|
= H.C.F. of |355 – 54|, |54 – 103| and |103 – 355|
= 301, 49, 252
= 7
1. 10
2. 20
3. 21
4. 25
```
 21 
```
Explanation:

L.C.M. of 3, 6, 9, 12, 15 and 18 is 180.
So, the bells will toll together after every 180 seconds(3 minutes).
In 60 minutes, they will toll together (60/3)+1 = 21 times.
1. 11121
2. 11011
3. 10010
4. 11000
```
 10010 
```
Explanation:

The smallest 5-digit number 10000.

10000 when divided by 11, leaves a remainder of 1

Hence add (11 – 1) = 10 to 10000
Therefore, 10010 is the smallest 5 digit number exactly divisible by 11
```
 474 
```
Explanation:

As

Therefore the given expression = (121 + 353) = 474
1. 0.025
2. 0.256
3. 0.0027
4. 0.00126
```
 0.0027 
```
Explanation:

Decimal of 10 hours in a minute
= 10 / (60 x 60)
= 0.0027
1. 10%
2. 20%
3. 40%
4. 50%
```
 50% 
```
Explanation:

Let the total work to be done is, say, 30 units.

A does the work in 10 days,
So A’s 1-day work = (30 / 10) = 3 units

B does the work in 15 days,
So B’s 1-day work = (30 / 15) = 2 units

Therefore, A’s and B’s together 1-day work = (3 + 2) = 5 units

In 3 days,
work done = 5 * 3 = 15 units
amount of work left = 30 – 15 = 15 units

Therefore the % of work left after 3 days = (15 / 30) * 100% = 50%
1. 2 hours
2. 2.5 hours
3. 3 hours
4. 3.5 hours
```
 3 hours 
```
Explanation:

Pump fills the tank in 1 hour

Time taken by Pump to fill due to leak = 1.5 hour
Therefore, in 1 hour, the amount of tank that the Pump can fill at this rate = 1 / (1.5) = 2/3

Amount of water drained by the leak in 1 hour = (1 – (2/3)) = 1/3

Therefore, the tank will be completely drained by the leak in (1 / (1/3)) = 3 hours
1. 5 min
2. 6.5 min
3. 7 min
4. 7.5 min
```
 7.5 min 
```
Explanation:

Let the total work to be done is, say, 60 units.

A fills the tank in 20 minutes,
So A’s 1-minute work = (60 / 20) = 3 units

B fills the tank in 30 minutes,
So B’s 1-minute work = (60 / 30) = 2 units

Therefore, A’s and B’s together 1-minute work = (3 + 2) = 5 units

Let the time when A and B both are opened be x minutes
and Since the total time taken to fill the tank is 15 minutes

Therefore, an expression can be formed as
5x + 3(15 – x) = 15
=> x = 7.5

Therefore, the B is turned off after 7.5 minutes
1. 7
2. 8
3. 8.5
4. 9
```
 9 
```
Explanation:

Current run rate = 4.5 in 6 overs
Runs already made = 4.5 * 6 = 27

Target = 153
Runs still required = 153 – 27 = 126
Overs left = 14

Therefore required run rate = 126 / 14 = 9
1. 0
2. 1
3. 9
4. 10
```
 9 
```
Explanation:

Let the 9 numbers be smaller than zero and let their sum be ‘s’

Now, in order to get the average 0, the 10th number can be ‘-s’

Therefore, average = (s + (-s))/10 = 0/10 = 0

  1. 21
  2. 19
  3. 23
  4. 20
```

```
 187 
```
  Explanation:
  
  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.
  1. (a)
  2. (b)
  3. (c)
  4. (d)
  5. (e)
```
 (b) 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. 
```
  Explanation:
  
  Given Statement II => x 2 – 3y 2 = 0
  => x 2 = 3y 2
  
  Putting the above in the question
  => (x 2 + y 2 ) 1/2
  => (3y 2 + y 2 ) 1/2
  => (4y 2 ) 1/2
  => ((2y) 2 ) 1/2
  => (2y)
  which is an integer as y is an integer
  1. (a)
  2. (b)
  3. (c)
  4. (d)
  5. (e)
```
 (a) 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. 
```
  Explanation:
  
  Given Statement I, 17th, of the month, is Saturday.
  Therefore 14th will be Wednesday
  1. If only assumption I is implicit
  2. If only assumption II is implicit.
  3. If either I or II is implicit.
  4. If neither I nor II is implicit.
  5. If both I and II are implicit.
```
 (e) Both I and II are implicit. 
```
  Explanation:
  
  Both the statements are implicit because since Ram is newly appointed in this company, so at the time of appointment, the performance of Ram is not well known. Also, they have to test performance over a span of time. So Ram (systems engineer) tries to prove his worth generally in the probation period. So, option (E) is correct.
  1. If only assumption I is implicit
  2. If only assumption II is implicit.
  3. If either I or II is implicit.
  4. If neither I nor II is implicit.
  5. If both I and II are implicit.
```
 (b) Only assumption II is implicit. 
```
  Explanation:
  
  The Assumption I might or might not be true according to the given Statement, but the Assumption II is definitely true. Hence only Assumption II is implicit.
  1. only conclusion I is true.
  2. only conclusion II is true.
  3. either conclusion I or conclusion II is true
  4. neither conclusion I nor conclusion II is true
  5. both conclusions I and II are true.

```
  Explanation:
  1. only conclusion I is true.
  2. only conclusion II is true.
  3. either conclusion I or conclusion II is true
  4. neither conclusion I nor conclusion II is true
  5. both conclusions I and II are true.
