Q1. The ratio of investments of two partners P and Q is 7:5 and the ratio of their profits is 7:10. If P invested the money for 5 months, find for how much time did Q invest the money?
Answer: 10 months
Explanation: Profit ratio = (investment × time). 7×5 : 5×t = 7:10; solving 35/(5t) = 7/10 gives t = 10 months.
