The true discount on a certain sum of money due 3 years hence is Rb. 250 and the simple interest on the same sum for the same time and at the same rate is Rs. 375. Find the sum and the rate percent.
T.D. = Rs. 250 and *.I. = Rs. 375.
Sum due =.I. x T.D./ .I. -T.D. = 375 x 250/375- 250 = Rs.750.
Rate=[100*375/750*3]%=16 2/3%
