A and B entered into a partnership by investing ₹16000 and ₹12000 respectively. After 3 months, A withdrew ₹5000 while B invested ₹5000 more. After 3 more months, C joined the business with a capital of ₹21000. If after one year, the profit is ₹26400, then by how much the share of B in the profit exceeds that of C ?

₹3600

ratio of profit of A , B and C = 147 : 189 : 126

= 7 : 9 : 6

Total profit = 22R = 26400

1R = 1200

Share of B in the profit exceeds that of C by = 9R - 6R = 3R

= 3 × 1200

= 3600

The correct answer is option (4) : ₹3600
