SOLUTION
Total capital of firm before retirement = 1,03,680+87,840+26,880 = Rs. 2,18,400
Availability of cash = 9,600-7,200 (Minimum Balance) = Rs. 2,400
Combined new capital of X and Z = Rs. 2,16,000
X’s new capital = 2,16,000 × 3/5 = Rs. 1,29,600
Existing capital of X = Rs. 1,03,680
So, X has to bring = 1,29,600−1,03,680 = Rs. 25,920
Z’s new capital = 2,16,000 × 2/5 = Rs. 86,400
Existing capital of Z = Rs. 26,880
So, Z has to bring = 86,400−26,880 = Rs. 59,520
