1) Shyam will complete work in 20 days. If Ram is 25% more efficient than Shyam, then how many days he will take to complete the work?

1. 14
2. 18
3. 16
4. 20

Explanation:

Work done by Shyam in one day = 1/20
Work done by Ram in one day = (1/20) × (125/100) = 5/80 = 1/16
So, Ram can complete the work in 16 days.

2) Manish is aged three times more than his son Suresh. After eight years, he would be two and a half time of Suresh's age. After further eight years, how many times would he be of Suresh's age?

1. 4 times
2. 5 times
3. 2 times
4. 3 times

Explanation:

Suppose that Suresh's present age= x
Then, Manish's present age =3x + x= 4x
After eight years, Manish's age= (2 + ½ ) times of Suresh's age
=> ( 4x + 8) = ( 2 + ½ ) ( x + 8)
=> 4x + 8 = 5/2 ( x + 8)
=> 8x + 16 = 5x + 40
=> 3x = 40 ? 16 =24
=> x = 24 / 3 = 8
After further eight years,
Suresh's age = x + 8+ 8= 8+ 8+ 8= 24
Manish's age = 4x+ 8+ 8= 4×8+ 8+ 8= 48
Manish's age/ Suresh's age = 48/24 = 2

3) A 2% error in excess is found while measuring the side of a square. So, find the percentage of error in the calculated area of the square.

1. 4.04%
2. 2.30%
3. 1.03%
4. 3%

Explanation:

Percentage error in the calculated area = (2+ 2+ (2×2/100))% = 4.04%

4) After rolling twice a dice, what will be the probability of getting a sum equals to 9?

1. 2/5
2. 3.4
3. 1/3
4. 1/9

Explanation:

Total number of possible outcomes of rolling a dice = 6
So, Total number of possible outcomes after rolling twice a dice, n(S) = 36
E = Getting sum of nine when two dice fall= { (3,6), (4,5), (5,4), (6,3) }
Hence, n(E) = 4
P(E)= n(E)/n(S)= 4/36 = 1/9

5) The Compound Interest on Rs. 30,000 at 7% per annum is Rs. 4347. The period(in years) is :

1. 1
2. 2
3. 3
4. 3.5

Explanation:

Let the period be n years
Then amount after n years= Rs.(30000+ 4347)= 34347
P(1+ R/100)^T = 34347
30000(1+ 7/100)^n = 34347
30000(107/100)^n = 34347
(107/100)^n = 34347/30000= 11449/10000= (107/100)^2
n = 2 years
