Question
Compound interest on a certain sum of money for 2 years
is Rs.3600 while the simple interest on the same sum for the same time period is Rs.3200. Find the rate of interest.Solution
SI for 1 year = 3200/2 = Rs.1600 Difference between CI and SI for 2 years = Rs.(3600 – 3200) = Rs.400 Required rate = (400/1600) x 100 = 25%
