Explanation

The interest gained from each mutual fund is proportional to the amount invested in each fund. The ratio of the investments is 15,000 : 5,000 : 25,000, which simplifies to 3 : 1 : 5. Dividing the total interest of Rs. 28,800 in this ratio yields Rs. 9,600, Rs. 3,200, and Rs. 16,000 respectively.

AI explanation

The investments are in the ratio 15000:5000:25000, which simplifies to 3:1:5. The total parts in this ratio is 3 + 1 + 5 = 9. Dividing the total interest of Rs 28,800 by 9 gives Rs 3,200 per part. Multiplying this value by the respective parts for each fund gives interests of Rs 9,600 for the first, Rs 3,200 for the second, and Rs 16,000 for the third.
