The ratio of ages of Son and Mother is 3 : 7 and the ratio of ages of Son and Father is 2 : 5. If the sum of the ages of Father and Mother is 58 years. Then find the present age of Son.1.10 years.2.12 years.3. 15 years.4. 18 years.5. 16 years.

Answer» Correct Answer - Option 2 :

12 years.

Given:

Ratio of ages of Son : Mother = 3 : 7

Ratio of ages of Son : Father = 2 : 5

Age _(M) + Age _(F) = 58 years

Calculation:

Son	Mother	Father
3_×2	_7×2
2_×3		5_×3
6	14	15

Let the ages be 6x, 14x and 15x.

According to the question,

Age _(M) + Age _(F) = 58yrs.

⇒14x + 15x = 58yrs.

⇒ 29x = 58

⇒ x = 2

⇒ Age of a Son = 6x

⇒ 6 × 2 = 12 years

∴ Age of a son is 12 years.
