Question

find the amount and compound interest on RS 7400 for 1 year at 5% per annum interest payable half yearly

Answer 1

Given Principal = 7400 rupees, r = 5%, n = 1 year.

Given that Interest is compounded half-yearly.

We know that A = P(1 + r/2 * 100)^n * 2

                            = P(1 + 5/200)^1 * 2

                            = 7400(1 + 1/40)^2

                            = 7400(41/40)^2

                            = 7400(1681/1600)

                            = 12439400/1600

                            = 7774.625.


Therefore, Amount = 7774.625.


We know that C.I = A - P

                             = 7774.625 - 7400

                             = 374.625.


Therefore, Compound Interest = 374.625.



Hope this helps!
