Q1. A began business with Rs.45000 and was joined afterwards by B with Rs.54000. When did B join if the profits at the end of the year were divided in the ratio of 2:1?
Answer: 7 months
Explanation: Profit ratio 2:1 means 45000×12 : 54000×t = 2:1; 540000 = 108000t → t = 5 months; B joined after 12−5 = 7 months.
