Let the total profit be \( P \). The profit is distributed in proportion to the amounts invested by A, B, and C.
The investment ratio is:
\[
A : B : C = 52,000 : 56,000 : 70,000
\]
Simplifying the ratio:
\[
A : B : C = 52 : 56 : 70
\]
We can divide by 2 to make the ratio simpler:
\[
A : B : C = 26 : 28 : 35
\]
Let the total profit be \( P \). The share of profit for each is proportional to their investment, so the difference between B's and C's shares in the profit is:
\[
\frac{28}{89}P - \frac{35}{89}P = 12,250
\]
This simplifies to:
\[
\frac{7}{89}P = 12,250
\]
Solving for \( P \):
\[
P = \frac{12,250 \times 89}{7} = 1,55,750
\]
Thus, the total profit is ₹1,55,750.
