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
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.
T.D. = Rs. (960 - 750) = Rs. 210.
Thus, S.I. on R.s 750 for 2 years is Rs. 210.
| Rate = |
 |
100 x 210 |  % |
= 14% |
| 750 x 2 |

It is said that SI = TD.
So we can calculate the rate by comparing this equality given in this question.

S.I = PW * r * t /100.
T.d = amount * r * t/100 + r * t.
As given S.I = T.d .
750 * r * 2/100 = 960 * r * 2 / 100 + r * 2.
R = 14.
T.d = amount * r * t/100 + r * t.
As given S.I = T.d .
750 * r * 2/100 = 960 * r * 2 / 100 + r * 2.
R = 14.
