If Rs. 10 be allowed as true discount on a bill of Rs. 110 due at the end of a certain time, then the discount allowed on the same sum due at the end of double the time is:
Answer: Option
Explanation:
S.I. on Rs. (110 - 10) for a certain time = Rs. 10.
S.I. on Rs. 100 for double the time = Rs. 20.
T.D. on Rs. 120 = Rs. (120 - 100) = Rs. 20.
| T.D. on Rs. 110 = Rs. |  |
20 | x 110 |  |
= Rs. 18.33 |
| 120 |

The discount allowed on the same sum 110 is double the time means 10 becomes 20%
So, 20% will come.
Therefore, principal amount is 100 for both the cases
(20x 110)/120= Rs. 18.33
So, 20% will come.
Therefore, principal amount is 100 for both the cases
(20x 110)/120= Rs. 18.33
