Question

rupees 62500 for 2years 6months at 12 percent per annum compounded anually

Answer 1

The formula for annual compound interest, including principal sum, is:
$A = P (1 + r/n {)}^{(nt)}$

Where:

A = the future value of the investment/loan, including interest
P = the principal investment amount (the initial deposit or loan amount)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per year
t = the number of years the money is invested or borrowed for
