The ratio of the present ages of a son and his father is 1 : 5 and that of his mother and father is 4 : 5. After 2 years the ratio of the age of the son to that of his mother becomes 3 : 10. What is the present age of the father?

30 years

28 years

37 years

35 years

Explanation:

SON : FATHER = 1 : 5

FATHER : MOTHER = 5 : 4

S : f : m = 1 : 5 : 4 ⇒ x : 5x : 4x

⇒ (x+2)/(4x+2)=3/10

⇒ 10x+20=12x+6

⇒ x= 7

Father’ age ⇒ 7 × 5 = 35 years
