Compound interest compounded annually on a certain sum of money for 2 years at 4 percent per annum is Rs 102 The simple interest on the same sum for the same rate and for the same period will be?

100 would be the interest if calculated with simple rate and the principal amount is 1250.

amount=P(1+R/100)^n

amount=P(1+4/100)^2

P+CI=P(104/100)^2

CI=P(204*4/100^2)

102=P(204*4/100^2)

P=102/(204*4/100^2)

THEREFORE SI=PTR/100

SI=100.........
