A and B started a business with initial investments in the ratio 14 : 15 and their annual profits were in the ratio 7 : 6. If A invested the money for 10 months, for how many months did B invest his money?
Suppose A invested Rs. 14a for 10 months and B invested Rs. 15a for b months.
14a x 10 / 15a x b = 7/6
b = 840 / 105 = 8
Hence, B invested the money for 8 months.
