Question

is simple interest and compound interest same ?how?

Answer 1

no. they are different compound interest is interest on simple interest

Answer 2

no bcoz Simple Interest = Principal amount (P) x Interest Rate (I) x Term of loan or deposit (N) in years.

Generally, simple interest paid or received over a certain period is a fixed percentage of the principal amount that was borrowed or lent.
compound interest compound interest accrues on the principal amount and the accumulated interest of previous periods; it includes interest on interest, in other words. It is calculated by multiplying the principal amount by the annual interest rate raised to the number of compound periods, and then minus the reduction in the principal for that year. Or as a formula:

Compound Interest = Total amount of Principal and Interest in future less Principal amount at present
