P's capital for the first 4 months = ₹1,00,000 P's capital for the next 8 months = ₹80,000 Q's and R’s capitals remain constant. Effective capital of P = (1,00,000 × 4) + (80,000 × 8) = ₹8,00,000 Effective capital of Q = 1,50,000 × 12 = ₹18,00,000 Effective capital of R = 2,00,000 × 12 = ₹24,00,000 Ratio of capitals = 8,00,000 : 18,00,000 : 24,00,000 = 2 : 4.5 : 6 P’s share of profit = (2/12.5) × 90,000 = ₹14,400 Correct Option: b)
