Question
A and B started a retail store with initial investments
in the ratio 8:9 and their annual profits were in the ratio 2:3. If A invested the money for 6 months, then for how many months did B invest his money?ÂSolution
Suppose A invested Rs. 8x for 6 months and B invested 9x for y months then, ⇒  (8x × 6)/(9x × y) = 2/3 ⇒  y = (48x × 3)/(9x × 2) ⇒  y = 144x/18x ⇒  y = 8
