1)An Amount of money grows upto Rs.5100 in 2 years & upto Rs.5800 in 3 years on compound interest.Find the rate percent?
There is a simple method to solve these kind problems
Rate=Difference between the amount/Amount in N year
Rate=700*100/5100
Rate=12.5%
Remember this Formula is applicable only if the difference between the year is 1 or the given year should be continuous
PRACTICE THIS SUM:
