3.	What percentage of simple interest per annum did Anand pay to Deepak?
	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 rate be R% p.a.

I gives, P = Rs. 8000 and T = 4 years.

II gives, S.I. = Rs. (8800 - 8000) = Rs. 800.

R =	(	100 x S.I.	)	=	(	100 x 800	)%	= 2	1	% p.a.
		P x T				8000 x 4			2

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