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

Solution

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.

	C.  20 years
	D.  22 years

Solution

Let the son's present age be x years .Then, man's present age = (x+24)years. Then ‹=›(x+24)+2= 2(x+2) ‹=›x+26=2x+4 x= 22.
