Question

Rahul's father is thrice as old as Rahul, after $12$ years he will be just twice his son. Find their present ages.

Answer 1

Let the age of father be $x$

the age of rahul be $y$

according to the given conditions

$x=3y$

$(x+12)=2(y+12)⟹x-2y=12⟹3y-y=12⟹y=12,x=3\left(12\right)=36$

$\therefore$ the age of father is $36$ and rahul's is $12$
