In a partnership business the monthly investment by three friends for the first six months is in the ratio 3: 4: 5. After six months, they had to increase their monthly investments by 10%, 15% and 20%, respectively, of their initial monthly investment. The new investment ratio was kept constant for the next six months.
What is the ratio of their shares in the total profit (in the same order) at the end of the year such that the share is proportional to their individual total investment over the year?
- 22: 23: 24
- 22: 33: 50
- 33: 46: 60
- 63: 86: 110
Correct answer: 63: 86: 110
Solution
The correct option reflects the total investments made by each partner over the year, accounting for both their initial investments and the increases after six months. By calculating the total contributions based on the given ratios and the percentage increases, we find that the final ratio of their shares in the profit aligns with 63: 86: 110.
