Question

The difference between simple interest and compound interest on a certain sum is rs 54.40 for 2 years at 8 percent per annum.find the sum

Answer 1

S.I for 2 years = P*R*T/100 = P*8*2/100 = 4*P/25
C.I for 2 years = P*(1 + R/100)^n - P
                        = P*(1 + 8/100)^2 - P
                        =P*(1 + 2/25)^2 - P = P*(27/25)^2 - P = 729*P/625-P
C.I - S.I = 54.40
54.40 = 729*P/625 - P - 4*P/25
54.40 = 729*P - 625*P-4*25*P/625
625*54.40 = P(729-625-100)
625*54.40 = P* 4
P = 8,500
