Question

How to find the number of days when principal amount and interest amount are given?

Answer 1

P=IRate⋅TimeP=IRate⋅Time

where,

P means Principal

I means Interest

Also, the future amount is the sum of the principal and the interest. Therefore, the principal is just the difference between the future amount and the interest.

P = Future Amount - Interest

If only the future amount, time and interest rate are given, we can use the following formula to calculate the principall.

P=FutureAmount1+(Rate⋅Time)P=FutureAmount1+(Rate⋅Time)

where,

P means Principal
