Correct Answer: 24,380
Solution : For the first investment, Principal = INR 4,400 Rate = 10% Time = 12 years Simple interest = $\frac{\text{Principal × Rate × Time}}{100}$ = $\frac{4400 \times 10 \times 12}{100}$ = INR 5,280 Amount received = 4400 + 5280 = INR 9680 For the second investment, Principal = INR 7,500 Rate = 8% Time = 12 years Simple interest = $\frac{7500 \times 8 \times 12}{100}$ = INR 7,200 Amount received = 7500 + 7200 = INR 14,700 The total amount received from the two investments = 9680 + 14700 = INR 24,380 Hence, the correct answer is 24,380.
