Let the father's age be X years and that son's b y years. Then, x+2y=70 ........(1) 2x+y=95 ........(2) Multiple (1) by 2, we get 2x+4y=140 ........(3) Subtracting(2) from(3), we get 3y=45 or y=15 putting the value of Y in equation (1) x+30=70 x=40 Hence father's age is 40 years and the son's age is 15 years
