Question

The sum of the ages of Rinku and Gopal is 40 yr. 5 yr hence, the ratio of their ages will be 3 : 7. The age of Rinku is ?

Answer 1

Step-by-step explanation:

let the Rinkus age be X and Gopals age be 40 - X ( because sum of their ages is 40)

after 5 years Rinkus age = X +5

Gopals age be ( 40- X) + 5

their ratios = 3:7 = 3/7

3/7 = X + 5 / ( 40 - X) + 5

Rinkus age = X + 5

X + 5=3

X= 5-3

X = 2

his age = X + 5 = 2+5= 7
