2. 32 years
3. 36 years
4. 38 years
5. 40 years

Answer 1

Correct Answer - Option 4 : 38 years

Given:

Radha present age is 6/5 times her age at the time of marriage.

Radha is married 8 years ago.

Radha's sister was 10 younger to her at the time of marriage.

Calculation:

Let the age Radha at the time of marriage be 5x.

The present age of Radha = 6/5 × 5x = 6x

Radha is married 8 years ago.

⇒ 6x - 5x = 8

⇒ x = 8

Radha age at the time of marriage = 5 × 8 = 40

Radha's sister age at the time of marriage = 40 - 10 = 30 years

Radha's sister present age = 30 + 8 = 38 years

∴ The present age of Radha's sister is 38 years.
