A and B starts a business with different capitals.A was to get 15% of the profit as salary and the rest was to be divided in the ratio of their investments.had the entire profit been distributed in the ratio of their investments,B would have got rupees 1350 more than what
he actually got.what is B's actual share of profit?

Sol: Let the profit be P and the ratio of profits of A and B is : A: B

Therefore, the profit B would have got is: B/A+B * P……………………………………..(1)

However, A gets 15% of the profit as a salary, so the remaining profit is 0.85P.

Now, the profit gets by B is: B/A+B *0.85P………………………………………….(2)

Subtract (2) from (1)

0.15BP/A+B = 1,350

BP/A+B=9,000

Put this value in Eq. (2)

The profit get by B is: 9,000 * 0.85 = 7,650
