At 12% simple interest per annum, Sunitha lent Rs. 4, 000 to Rohan for 3 years and Rs. 5, 000 to Priyanka for 2 years . Calculate the total interest Sunitha earned from both loans.

Solution & Step-by-step Explanation

The formula for Simple Interest (SI) is: SI = \frac{P \times R \times T}{100} 1. **Calculate the interest from Rohan's loan (SI_{1}):** * P_{1} = Rs. 4, 000 * R = 12% * T_{1} = 3 years SI_{1} = \frac{4000 \times 12 \times 3}{100} = 40 \times 36 = Rs. 1, 440 2. **Calculate the interest from Priyanka's loan (SI_{2}):** * P_{2} = Rs. 5, 000 * R = 12% * T_{2} = 2 years SI_{2} = \frac{5000 \times 12 \times 2}{100} = 50 \times 24 = Rs. 1, 200 3. Calculate total interest: Total Interest = SI_{1} + SI_{2} = 1, 440 + 1, 200 = Rs. 2, 640
