Question

A father is three times as old as his son . In 15 years time he will be twice as old as his son. how old is the father now?

Answer 1

Step-by-step explanation:

if, father= X

the , son= Y

so, X= 3Y

Hence, (X+15) = 2(y+15)

so, X=2Y+15

hence, 3Y=2Y+15. ( By replacing ) X=3y

so, Y= 15

son age = 15years

Fathers age= 3Y

= 3*15= 45 years
