Question

# Find out the simple interest on Rs. 7500 for 2 ½ years at 15 % per annum. Also find the amount

Hint:

### Find the simple interest and then add it with the principal amount to get the total amount.

## The correct answer is: 10437.5 Rupees

### Complete step by step solution:

We calculate simple interest by the formula,…(i)

where P is Principal amount, T is number of years and R is rate of interest

Let the sum of money P = 7500 Rs

Here, we have T = 2.5 years, and P = 7500 Rs

On substituting the known values in (i), we get

We have SI = 2937.5 Rupees.

We know the formula for total amount = A = P + SI…(ii)

where A is the total amount, P is the principal amount and SI is simple interest.

On substituting the known values in (ii), we get A = 7500 + 2937.5 = 10437.5

Hence the simple interest = 2937.5 Rupees

And total amount = A = 10437.5 Rupees.
