Answer 2

Answer:

Step-by-step explanation:

The formula for SI = Pnr/100

Given SI = Rs. 450, n = 2 and r = 4%, we have

450 = 2*4*P/100

Or P = 450*100/(2*4) = 5625.

CI for the same interest rate for 1 year, compounded every half yearly can be given by the formula

A = P(1+r/100)^n.

Here, P = 5625, r = 4/2 = 2% and n = 2, since there are two half-yearly compounding of the amounts.

Thus A = 5625*(1+2/100)^2 = 5625*1.02)^2 = 5625*1.0404 = 5852.25

Therefore, the compound interest is A - P = 5852.25-5625 = 227.25.

Thus, the CI for Rs. 5625 at 4% compounded half-yearly is Rs. 227.25.
