Step 1: Calculate the Total Capital of the New Firm:
New Ratio (Kajal : Laura : Maddy) = 2 : 1 : 1. Maddy's share is \( \frac{1}{4} \).
Maddy's Capital = Rs 8,00,000 for \( \frac{1}{4} \) share.
Total Capital of the firm (based on Maddy's capital) = Maddy's Capital / Maddy's Share
Total Capital = Rs 8,00,000 / \( \frac{1}{4} \) = Rs 8,00,000 \( \times \) 4 = Rs 32,00,000.
Step 2: Calculate Kajal's Required Capital in the New Firm:
Kajal's share in the new ratio = \( \frac{2}{4} \) (from 2:1:1).
Kajal's Required Capital = Kajal's New Share \( \times \) Total Capital
Kajal's Required Capital = \( \frac{2}{4} \times 32,00,000 = Rs 16,00,000 \).
Step 3: Determine the Cash Adjustment for Kajal:
Kajal's Existing Capital (after all adjustments) = Rs 15,00,000.
Kajal's Required Capital = Rs 16,00,000.
Since Required Capital $>$ Existing Capital, Kajal needs to bring in cash.
Cash to be brought in by Kajal = Required Capital - Existing Capital
Cash to be brought in by Kajal = Rs 16,00,000 - Rs 15,00,000 = Rs 1,00,000.
Conclusion:
The cash brought in by Kajal was Rs 1,00,000.
