SIMPLE INTEREST :
A sum of money doubles itself in ten years at simple interest. Find the rate of interest?
Let the sum of money that's principal be P.
Time = 10 years
Amount after 10 years becomes double = 2P
Therefor, Simple Interest = Amount - Principal = 2P-P = P
Rate per annum = SI×100/ P×T = P×100/P×10 = 100/10 = 10%;
