If the compound interest on a sum for 2 years at 12.5% p.a. is Rs 510, find the simple interest on the same sum at the same rate for the same period.
ARs 400
BRs 450
CRs 480
DRs 500
✓ Correct Answer: C — Rs 480
12.5% = 1/8. CI = P[(9/8)^2 - 1] = P[17/64]. 510 = 17P/64 => P = 1920. SI = (1920 * 2 * 12.5)/100 = 480.
