2.	What is the sum which earned interest?
	A.	I alone sufficient while II alone not sufficient to answer
	B.	II alone sufficient while I alone not sufficient to answer
	C.	Either I or II alone sufficient to answer
	D.	Both I and II are necessary to answer

Answer: Option D

Explanation:

Let the sum be Rs. x.

I gives, S.I. = Rs. 7000 and T = 7 years.

II gives, Sum + S.I. for 5 years = 2 x Sum Sum = S.I. for 5 years.

Now, S.I. for 7 years = Rs. 7000.

S.I. for 1 year = Rs.	7000	= Rs. 1000.
	7

Thus, I and II both are needed to get the answer.
