What is Sonia's present age?

I. Sonia's present age is five times Deepak's present age.

II. Five years ago her age was twenty-five times Deepak's age at that time.

II alone sufficient while I alone not sufficient to answer

Either I or II alone sufficient to answer

Both I and II are not sufficient to answer

Both I and II are necessary to answer

I. S = 5D D =	S	....(i)
	5

II. S - 5 = 25 (D - 5) S = 25D - 120 ....(ii)

Using (i) in (ii), we get S =		25 x	S		- 120
			5

4S = 120.

S = 30.

Thus, I and II both together give the answer. So, correct answer is (4).
