Question

The present age of a father is 3 years more than 3 times the age of the son 3 years hence father's age will be 10 years more than twice the age of the son determine their present age

Answer 1

Let the age of son after 10 year bex
let the fathers age after 10 year be2x
So present age of son=x+3
and present age of father=3(2x+3)
3(2x+3)=x+3
6x+3=x+3
x=5
present age of son=5+3= 8
present age of father=3(2×5+3)
=6+15+9
=30
