5)Father is aged three times more than his son Sunil. After 8 years, he would be two and a half times of Sunil’s age. After further 8 years, how many times would he be of Sunil’s age?
a) 4 times
b) 4 times
c) 2 times
d) 3 times

Answerc) 2 times
Assume that Sunil’s present age = x.
Then father’s present age = 3x + x = 4x
After 8 years, father’s age = 212212 times of Sunils’ age
=(4x+8) = 2(1/2)(x+8)
=4x + 8 = 5/2(x + 8)
=8x + 16 = 5x + 40
=3x = 40 – 16 = 24
=x = 24/3 = 8
After further 8 years,
Sunil’s age = x + 8 + 8 = 8 + 8 + 8 = 24
Father’s age = 4x + 8 + 8 = 4 × 8 + 8 + 8 = 48
