A and B start a business with initial investment in the ratio 12 : 11 and their annual profits were in the ratio 4 : 1. If A invested the money for 11 months . B invested the money for?
Correct Answer: 3 months
Explanation:
Suppose B invested the money for N months.
Then the ratio of investment = (12 x 11 : 11 x N) = 12 : N
∴ 12/N = 4/1
⇒ N = 3 months.
