If a person deposit money into two banks at 6 Tk interest respectively, the difference in profit after three and half years and five years 144. How much money did the person deposit?
Let the amount deposited in each bank be x. Then, the difference in interest after three and a half years and five years is: (x65/100) - (x63.5/100) = 144 => x*6(5 - 3.5)/100 = 144 => x = 144 * 100/6 * 1.5 => x = 1600 So the answer is 1600
