Answer 1

Answer:

The ratio of the father's and son's age is 7 : 4. the product of their ages is 1008. The ratio of their ages after 6 years later will be ?

5 : 3

8 : 5

7 : 4

5 : 8

Correct Option: B

Let father's and son's age be 7x and 4x respectively

∵ 28 x2 = 1008

⇒ x2 = 36

⇒ x = 6

∴ Father's age = 7x = 42 years

Son's age = 4x = 24 years

Father's age after 6 years later = 48 years

Son's age 6 years hence = 30 years

Required ratio = 48 : 30 = 8 : 5
