Q1. A and B start a business with investments in the ratio 3:5. After 4 months, C joins with an investment in the ratio 2:3 with B. What is A's share in the profit at the end of the year?
Answer: 3/8
Explanation: A's investment = 3x * 12, B's = 5x * 12, C's = 3y * 8 (since y = 5x/3, C's = 5x * 8/3 * 3 = 8x * 5/3 but we actually compare it with B, so 2/3 * 5x = 10x/3, and for 8 months.
