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

Answer: Option B

S.I. on Rs. 750 = T.D. on Rs. 960
This means P.W. of Rs. 960 due 2 years hence is Rs. 750
∴ T.D. = Rs. (960 - 750) = Rs. 210
Thus, S.I. on R.s 750 for 2 years is Rs. 210
$$\begin{array}{rl}& \therefore \text{Rate}=\left(\frac{100\times 210}{750\times 2}\right)\%\\ & =14\%\end{array}$$
