|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|
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] / [p x t ]= (100 x 800)/(8000 x 4) = 2 ½ % p.a
Thus, I and II both are needed to get the answer.
