Answer 2

• Let present age of son be M.

» The age of a father is three times of his son.

• Age of father = 3M

» 5 years ago

• Age of son = M - 5

• Age of father = 3M - 5

» 5 years ago father was five times as old as his son.

A.T.Q.

=> 3M - 5 = 5(M - 5)

=> 3M - 5 = 5M - 25

=> 3M - 5M = - 25 + 5

=> - 2M = - 20

=> 2M = 20

=> M = 10

______________________________

$\textbf{Present age of son = M = 10 years.}$

$\textbf{Present age of father = 3M = 3(10)}$

$\textbf{= 30 years}$
