Question

find the interest on a sum of rs.8250 for 3 years at the rate of 8% per annum

Answer 1

interest = principal * rate * time

i = 8250* 8/100 *3
i = 1980

Answer 2

We have : P = rs. 8250, R = 8% per annum, T = 3 years.

so, S.I. = $\frac{P×R×T}{100}$

= rs. $\frac{8250×8×3}{100}$

= 1980.

Amount = Principal + S.I. = rs. (8250 + 1980) = rs. 10230.
