Question

The current age ratio of father and son is 2: 1 . Ten(10) years ago, their age ratio was 5: 2 What Is Son's Present Age ?​

Answer 1

Answer:

let current age of father is 2x years

so current age of son is x years

10 years ago ,father was (2x-10)years old

10 years ago son was (x-10) years old

so,

( 2x-10) : (x-10) =5 : 2

(2x-10)/(x-10)=5/2

=> 5(x-10)=2(2x-10)

=> 5x-50=4x-20

=> 5x-4x= -20+50

=> x=30

son's present age is 30 years
