Question

Raju age after 15 years will be 5 times his age 5 years back, what is the present age of Raju?
1. 14 years
2. 15 years
3. 8 years
4. 10 years

Answer 1

Correct Answer - Option 4 : 10 years

Given:

Raju's age after 15 years = 5 times Raju's age 5 years back

Calculations:

Let Raju's present age be x years

⇒ (x + 15) = 5 × (x – 5)

⇒ (x + 15) = (5x – 25)

⇒ 5x – x = 15 + 25

⇒ 4x = 40

⇒ x = 10 years

∴ The present age of Raju is 10 years
