The difference between the interest earned under compound interest, interest being compounded annually and simple interest for two years on the same sum and at the same rate of interest is Rs.25.60. Find the sum if the rate of interest is 8% p.a.
Rs.2000
Rs.2500
Rs.3200
Rs.4000
Difference between S.I and C.I = 25.60 Rs.
Because B is calculated A at same rate at which A is calculated On P
i.e 8%
so B is 8 % of A , then A
= (25.60/8 ) x 100 = 320
And A is 8 % of p then P = 320 / 8 = 4000 Rs.
