Q.

Rajeev's age after 15 years will be 5 times his age 5 years back. What is the present age of Rajeev                         


A. 5 Years B. 10 Years
C. 20 Years D. 25 Years

Answer: Option B
Explaination:

 


Let Rajeev's present age be x years. Then


Rajeev's age 15 years = (x+15) years.

Rajeev's age 5 years back = (x-5) years.

Therefore <=> x+15=5(x-5)

<=> x+15= 5x-25

<=> 4x=40

<=> x = 10.
