Rs. 20 is the true discount on Rs. 260 due after a certain time. What will be the true discount on the same sum due after half of the former time, the rate of interest being the same?
Answer: Option
Explanation:
S.I. on Rs. (260 - 20) for a given time = Rs. 20.
S.I. on Rs. 240 for half the time = Rs. 10.
T.D. on Rs. 250 = Rs. 10.
 T.D. on Rs. 260 = Rs. |
 |
10 | x 260 |  |
= Rs. 10.40 |
| 250 |

Please explain how this method is wrong
Amount is 260
PW would be (260-20)=240
20=240xrxt/100
rt=100/12
if t=t/2
TD=240 x r x t/2 x r/100
TD=240 x 100/2400
TD=10
