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?
Correct Answer: Rs. 10.40
Explanation:
S.I. on Rs. 240 for a given time = Rs. 20
S.I. on Rs. 240 for half the time = Rs. 10
∴ Rs. 10 is T.D. on Rs. 250
So, T.D. on Rs. 260 = Rs. (10 / 250) x 260 = Rs. 10.40
