What amount of money invested would earn an interest of Tk 200 over 4 years at 10% simple interest rate?
To calculate the principal amount required to earn an interest of Tk 200 over 4 years at 10% simple interest rate, we can use the following formula:
Principal = Interest / (Rate of interest * Time)
Substituting the given values, we get:
Principal = 200 / (10/100 * 4)
Principal = 200 / 0.4
Principal = Tk. 500
Therefore, the principal amount required to earn an interest of Tk 200 over 4 years at 10% simple interest rate is Tk. 500.
So the answer is 500
