This problem involves calculating the distribution of a total profit based on the investment ratios of partners. The profit earned by each partner is directly proportional to their investment.
The investment ratio for partners A, B, and C is given as 61 : 43 : 90.
To find the total value represented by these ratios, we sum them up:
Total Ratio Parts = $61 + 43 + 90 = 194$
The total profit earned at the end of the year is ₹2,910.
This total profit corresponds to the sum of the ratio parts (194).
We can find the profit amount represented by one part of the ratio by dividing the total profit by the total ratio parts:
Value of 1 Ratio Part = Total Profit / Total Ratio Parts
Value of 1 Ratio Part = $₹2,910 / 194$
Value of 1 Ratio Part = $₹15$
Now we can find the profit share for each partner:
Checking the total: $₹915 + ₹645 + ₹1350 = ₹2910$, which matches the total profit.
The question asks for the difference between the share of B and C.
Difference = C's Share - B's Share
Difference = $₹1350 - ₹645$
Difference = $₹705$
We can also calculate the difference directly using the ratio parts:
Difference in Ratio Parts (C - B) = $90 - 43 = 47$
Difference in Profit = Difference in Ratio Parts * Value of 1 Ratio Part
Difference in Profit = $47 * ₹15$
Difference in Profit = $₹705$
Both methods confirm that the difference between the share of B and C is ₹705.
