1.

The difference between compound interest and simple interest on an amount of Rs. 15,000 for 2 years is Rs. 96. What is the rate of interest per annum?

A.
8
B.
10
C.
12
D.
Cannot be determined
E.
None of these

Your Answer: Option (Not Answered)

Correct Answer: Option A

Explanation:

15000 x 1 + R 2 - 15000 - 15000 x R x 2 = 96
100 100

15000 1 + R 2 - 1 - 2R = 96
100 100

15000 (100 + R)2 - 10000 - (200 x R) = 96
10000

R2 = 96 x 2 = 64
3

R = 8.

Rate = 8%.

A number consists of two digits. If the digits interchange places and the new number is added to the original number, then the resulting number will be divisible by:

A.
3
B.
5
C.
9
D.
11

Your Answer: Option (Not Answered)

Correct Answer: Option D

Explanation:

Let the ten's digit be x and unit's digit be y.

Then, number = 10x + y.

Number obtained by interchanging the digits = 10y + x.

(10x + y) + (10y + x) = 11(x + y), which is divisible by 11.

Correct Answer: Option C

Explanation:

I gives, h = 28 m and r = 14.

Capacity = r2h, which can be obtained.

Thus, I alone gives the answer.

II gives, r2 = 616 m2 and h = 28 m.

Capacity = (r2 x h) = (616 x 28) m3.

Thus, II alone gives the answer.

Correct answer is (C).

The sum of the present ages of a father and his son is 60 years. Six years ago, father's age was five times the age of the son. After 6 years, son's age will be:

A.
12 years
B.
14 years
C.
18 years
D.
20 years

Your Answer: Option (Not Answered)

Correct Answer: Option D

Explanation:

Let the present ages of son and father be x and (60 -x) years respectively.

Then, (60 - x) - 6 = 5(x - 6)

54 - x = 5x - 30

6x = 84

x = 14.

Two goods train each 500 m long, are running in opposite directions on parallel tracks. Their speeds are 45 km/hr and 30 km/hr respectively. Find the time taken by the slower train to pass the driver of the faster one.

A.
12 sec
B.
24 sec
C.
48 sec
D.
60 sec

Your Answer: Option (Not Answered)

Correct Answer: Option B

Explanation:

Relative speed = = (45 + 30) km/hr
= ( 75 x 5 ( m/sec
18
= ( 125 ( m/sec.
6

We have to find the time taken by the slower train to pass the DRIVER of the faster train and not the complete train.

So, distance covered = Length of the slower train.

Therefore, Distance covered = 500 m.

Therefore Required time = ( 500 x 6 ( = 24 sec.

Which of the following has the most number of divisors?

A.
99
B.
101
C.
176
D.
182

Your Answer: Option (Not Answered)

Correct Answer: Option C

Explanation:

99 = 1 x 3 x 3 x 11

101 = 1 x 101

176 = 1 x 2 x 2 x 2 x 2 x 11

182 = 1 x 2 x 7 x 13

So, divisors of 99 are 1, 3, 9, 11, 33, .99

Divisors of 101 are 1 and 101

Divisors of 176 are 1, 2, 4, 8, 11, 16, 22, 44, 88 and 176

Divisors of 182 are 1, 2, 7, 13, 14, 26, 91 and 182.

Hence, 176 has the most number of divisors.
