Rajeev's age after 15 years will be 5 times his age 5 years back. What is the present age of Rajeev?
Explanation:
Let Rajeev's present age be x years.
∴ Rajeev's age after 15 years = (x + 15) years. Rajeev's age 5 years back = (x - 5) years.
⇒ x + 15 = 5 × (x - 5) ⇒ x + 15 = 5x - 25 ⇒ 4x = 40 ⇒ x = 10.
∴ Rajeev's present age = 10 years.
Hence, 10.
