__FORMULAE__

__SIMPLE INTEREST:__**1. I=PNR/100**

I=Interest P=Principal N=Number of years

2.R=100 I/PN

3.N=100 I/PR

4.P=100 I/NR

5.Total Amount (A)=Principal+Interest

__COMPOUND INTEREST:__
In compound interest, interest is
calculated after every term and added with the previous sum. Let p be the principal
r, be the rate of interest and n be the time.

Amount =P(1+r/100)

^{n}
Interest =P(1=r/100)-p
