Answer:
To find the sum, we can use the formula for simple interest:
Simple Interest = (Principal) x (Rate) x (Time)
Given that Kumaravel has paid a simple interest of 750 for 2 years at a rate of 10% per annum, we can set up the equation as follows:
750 = (Principal) x 0.10 x 2
To find the Principal, we can rearrange the equation and solve for it:
Principal = 750 / (0.10 x 2)
Principal = 750 / 0.20
Principal = 3750
Therefore, the sum that Kumaravel has paid the simple interest on is 3750.
