Step 1: Distribute profit as per the profit-sharing ratio:
The total profit available is Rs.1,10,000. Distribute the profit among Mahi, Ruhi, and Ginni in the ratio \(6 : 4 : 1\):
\[
{Mahi’s Share: } Rs.1,10,000 \times \frac{6}{11} = Rs.60,000.
\]
\[
{Ruhi’s Share: } Rs.1,10,000 \times \frac{4}{11} = Rs.40,000.
\]
\[
{Ginni’s Share: } Rs.1,10,000 \times \frac{1}{11} = Rs.10,000.
\]
Step 2: Calculate Ginni’s guaranteed amount and shortfall:
Ginni is guaranteed a profit of Rs.50,000. Her allocated share is Rs.10,000, so the shortfall is:
\[
Rs.50,000 - Rs.10,000 = Rs.40,000.
\]
Step 3: Adjust Mahi’s share for the guarantee:
The shortfall of Rs.40,000 is borne by Mahi. Adjusting Mahi’s share:
\[
{Mahi’s Final Share: } Rs.60,000 - Rs.40,000 = Rs.20,000.
\]
Conclusion:
Mahi’s share in the profit of the firm after giving the guaranteed amount to Ginni is \( Rs.20,000 \).
