Explanation

Initial investments: 3x, 6x, 8x. New investments: 3x*1.05 = 3.15x, 6x*1.15 = 6.9x, 8x*1.20 = 9.6x. Ratio: 3.15 : 6.9 : 9.6. Multiply by 100/15: 21 : 46 : 64.

AI explanation

Assume the initial investments of Suresh, Dinesh, and Ramesh are 3x, 6x, and 8x. After the respective increases of 5%, 15%, and 20%, the new capitals become 3.15x, 6.9x, and 9.6x. To remove the decimals, multiply each value by 100 to get 315, 690, and 960. Dividing these values by their highest common factor of 15 yields a final profit ratio of 21 : 46 : 64.
