Question

Ten years ago, Sunil was half of Sudip's age. If the age of both at present is in the ratio of 3:4, what will be the total of their present age?

विकल्प

• 20 years

• 30 years

• 35 years

• 45 years

Answer 1

35 years

Explanation:

Let the present age be = 3x and 4x

`(3"x"-10)/(4"x"-10) =1/2`

6x − 20 = 4x − 10

2x = 10

x = 5

Sum of their age = 3x + 4x = 7x

= 7 × 5 = 35 years
