Question
P, Q, R invested in the ratio of 6 : 5 : 7. After the end of business term they receive the profit in the ratio 3 : 1 : 5. Find the ratio of time in which they invested in the business?
Solution
To find the ratio of time in which they invested in the business, we need to use the formula for profit sharing in a business partnership, which is:
Profit = Capital * Time
Given that the profit ratio is 3:1:5 and the capital ratio is 6:5:7, we can set up the following equations to find the time ratio:
For P: 6T1 = 3 (where T1 is the time P invested) For Q: 5T2 = 1 (where T2 is the time Q invested) For R: 7T3 = 5 (where T3 is the time R invested)
Solving these equations for T1, T2, and T3 gives us:
T1 = 3/6 = 0.5 T2 = 1/5 = 0.2 T3 = 5/7 = 0.714
So, the ratio of time in which they invested in the business is 0.5:0.2:0.714, which simplifies to 5:2:7.14. However, ratios are typically expressed in whole numbers. To convert this to whole numbers, we can multiply each term by 10, giving us a final time ratio of 5:2:7.14.
