If a genuine discount of Rs. 10 is permitted on a bill of Rs. 110 due at the end of a period of time, the discount allowed on the same quantity due at the end of a period of time twice as long is:
A. Rs. 20 B. Rs. 21.81 C. Rs. 22 D. Rs. 18.33
Explanation: For a period of time, S.I. on Rs. (110 - 10) Equals Rs. 10For double the period, S.I. on Rs. 100 Equals Rs. 20.Rs. 120 T.D. = Rs. (120 - 100) = Rs. 20T.D. on Rs. 110 = Rs. 20/120 x 110 = Rs. 18.33 T.D. on Rs. 110 = Rs. 20/120 x 110 = Rs. 18.33
