Q:

The interest on Rs.750 for 2yrs is the same as the True Discount on Rs.960 due 2yrs hence . If the rate of interest is same in both cases,it is:

A) 12%	B) 14%
C) 15%	D) 16

Answer & Explanation Answer: B) 14%

Explanation:

S.I on Rs.750= T.D on Rs. 960

This means P.W of Rs. 960 due 2 years hence is Rs.750

Therefore , T.D= Rs. (960 - 750) = Rs. 210

Thus, S.I on Rs. 750 for 2 years is Rs. 210

Rate =[ (100 x 210) / (750 x 2) ] % = 14%
