ANSWERS

1. (3)

P = 29000 CI = 9352.5 N = 2 years A = P + I = 38,352.5

Substituting the values in

A = P(1 + R/100)^n

Solving we get R = 15%.

2. (2)

The required time will be the LCM of 8, 18 and 15 which is 360 sec or 6 minutes.

3. (3)

Π R^2 = 39424

R = 112

Perimeter of square = 4a = 112

Side of square = 112/4 = 28

Area of square = 28^2 = 784 cm2.

4. (1)

Number of ways = 5C2 * 6C2 *3C1 = 450

5. (4)

Number of ways = 11C2 * 3C3 = 55.

6. (3)

Required number of days = (30 * 36)/18 = 60

7. (4)

Let total income of Ram be x. Then

(100 – 50 – 20 – 5)% of x = 11250

x = 45000.

8. (5)

Let the number be xy

(10x + y) – (10y + x) = 54

x – y = 6 And x + y = 12

Solving the equations we get x = 9 and y = 3

So the number is 93.

9. (1)

Let the age of Geeta’s daughter be x. Then Geeta’s age is 8x.

(8x + 8)/(x + 8) = 10/3

x = 4

Geeta’s present age = 8x = 32 years.

10. (3)

Required number of ways = 4! * 3! * 2! = 288.
