Father is aged three times more than his son Ronti. After 8 years , he would be two and a half times of Ronti's age. After further 8 years, how many times would he be of Ronti's age?

Answer 1

f = 3r
f+8 = 5/2 (r+8)

r=24, so f=72
check: (72+8)/(24+8) = 80/32 = 5/2

So, (72+16)/(24+16) = 88/40 = 11/5
