| Ravi is 12 years younger than Surya. Ravi’s age is 40% of the sum of his and Surya’s age. What will be Surya’s age 9 years later?

A. 36

B. 24

C. 33

D. 45

### Right Answer is: D

#### SOLUTION

Let the age of Ravi and Surya be respectively.

A.T.Q.

∴ x=2 units and y=3 units

Ravi is 12 years younger than Surya

y – x = 12 yr

(3 – 2 ) unit = 12 yr

1 unit = 12 yr

Surya’s age 3 unit = 12 ×3 = 36 yr.

Required

Surya’s age after 9 yr = 36 + 9 = 45 yr.
