A and B invest 3,000 and 4,000 in a business. A receives 10 per month out of the profit as a remuneration for running the business and the rest of profit is divided in proportion to the investments. If in a year ‘A’ totally receives 390, what does B receive?  Choose the correct choice
A) 375	B) 360	C) 350	D) 260	E) None of these
In a year, for A, total amount as a remuneration   = 10 × 12 = 120   ∴ Amount of A’s profit = 390 – 120 = 270   Ratio of investment = 3 : 4   Let total profit = x   Then, 360’s profit = (x – 270)   ∴ 3/3+4×x=270⇒ x = 630   ∴ 360’s profit = 630 – 270 = 360   Answer 360
