If the true discount on s sum due 2 years hence at 14% per annum be Rs. 168, the sum due is:
|
| [A]. |
Rs. 768 | [B]. |
Rs. 968 | | [C]. |
Rs. 1960 | [D]. |
Rs. 2400 |
Answer: Option D
Explanation:
| P.W. = |
100 x T.D. |
= |
100 x 168 |
= 600. |
| R x T |
14 x 2 |
 Sum = (P.W. + T.D.) = Rs. (600 + 168) = Rs. 768.

Why pw=100*td/r*t
pw=100*td/(100+(r*t)) why not?
What the diff between these 2 formula's ? |

pw=100*amount/(100+(r*t))
@Kuldeep Amount is different from True discount.
In this problem he mentioned true discount but not amount. |
