Rishav takes a loan of Rs from a bank for a period of 1 year. Find the interest and the amount he has to pay at the end of a year.

In the formula for calculating compound interest, the variables “i” and “n” have to be adjusted if the number of compounding periods is more than once a year. Bank \(B\)’s monthly compounding is not enough to catch up with Bank \(A\)’s better APR.  Bank \(A\) offers a better rate.
