Q1. A began a business with Rs. 85,000. He was joined afterwards by B with Rs. 42,500. For how much period does B join, if the profits at the end of the year are divided in the ratio of 3 : 1?
Answer: 8 months
Explanation: A's investment-months = 85000×12 = 1020000; for a 3:1 profit ratio, B's share = 340000, so 42500×t = 340000, giving t = 8 months.
