11.
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 |

As we know rt = 1/12.
Rt/2 = 1/24.
T.d = amount * rt / 100 + rt.
= 260 * 1/24 / 100 + 1/24.
= 10.4.
Rt/2 = 1/24.
T.d = amount * rt / 100 + rt.
= 260 * 1/24 / 100 + 1/24.
= 10.4.

ptr/100 = SI.
240*tr = 2000.
Then tr = 2000/240.
Then how did you got that 1/12?
Please tell me.
240*tr = 2000.
