GIVEN: A started a business with Rs. 5600 and after a few months B joined with a capital of Rs. 6400. At the end of one year, the profit is divided in the ratio 3 : 2respectively. CONCEPT: Profit will be shared according to the Investment and the time for which the investment is done. CALCULATION: Suppose B joined for ‘x’ months: Ratio in which the profit will be shared between A and B =(5600×12):(6400×x) =672:64x = 21:2x As given the profit is divided in the ratio 3 : 2 respectively .⇒ 21:2x=3:2 ⇒ x=7 ∴ B joined after 5(=12–7) months from the start
