Rabert’s age after 15 years will be 5 times his age 5 years back. What is the present age of Rajeev? Choose the correct choice:
A) 10 years.	B) 11 years.	C) 12 years.	D) 13 years.	E) 14 years.
Sol. Let Rabert’s present age be x years. Then,   Rabert’s age after 15 years = (x + 15) years.   Rabert’s age 5 years back = (x - 5) years.   ∴ x + 15 = 5 (x - 5) ⇔ x + 15 = 5x - 25   ⇔ 4x = 40 ⇔ x = 10.   Hence, Rabert’ present age = 10 years.   10 years.nswer 10 years.
