A started a business by investing Rs. 85,000. Later, B joined with an investment of Rs. 42,500. For how many months did B invest if the profit sharing ratio at the end of the year is 3:1 in favor of A and B respectively?
Explanation
Since A invested Rs. 85,000 for 12 months and B invested Rs. 42,500 for x months, the profit ratio is given by (85000 × 12) : (42500 × x) = 3 : 1. Solving for x gives x = 8 months.
