8 years earlier there ages were as 13:4. Fathers
present age is?
A) 12
B.24
C.48
D.60
E. None of these

Answer 1

Step-by-step explanation:

Let Son's age = S

Father's age = F

then, F−10=3(S−10)

F=3S−20

and, F+10=2(S+10)

F=2S+10

Thus, 3S−20=2S+10

S=30 years

Hence, F=70 years

Hence required ratio = 7:3
