Father is aged three times more than his son Ronit. After 8 years, he would be two and a half times of Ronit's age. After further 8 years, how many times would he be of Ronit's age?
A.2 timesB.2 1times2C.2 3times4D.3 times
A.2 timesB.2 1times2C.2 3times4D.3 times
Let Ronit's present age be x years. Then, father's present age =(x + 3x) years = 4x years.
(4x + 8) =5(x + 8)2
 8x + 16 = 5x + 40
 3x = 24
 x = 8.
Hence, required ratio =(4x + 16)=48= 2.(x + 16)24
(4x + 8) =5(x + 8)2
 8x + 16 = 5x + 40
 3x = 24
 x = 8.
Hence, required ratio =(4x + 16)=48= 2.(x + 16)24
