Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

With I and II: Total investment = 22000, A's share = 5/11 = 10000. For 3 years, A's effective investment = 10000 × 3 = 30000. Profit = 3/8 × 22000 = 8250. A's share = (15/33) × 8250 = 3750. With III alone: Average profit = 2750, so total profit = 2750 × 3 = 8250, which matches. Both paths give the same result, so C is correct.
