A certain sum of money lent at a certain rate of compound interest grows to 1.44 times its value in 2 years. If the same sum is lent at simple interest at the same rate, in how many years would it double itself?

Solution

let the sum is x and compound interest rate is y %, then x*y*y/100*100 = 1.44x or y^2 = 14400 or y = 120 it means the sum will become 120 % in one year so interest rate = 20 %, so 5 years are required.
