‘A’ started a business by investing Rs. 1600. Three months later, ‘B’ joined by investing Rs. ‘x’. If at the end of the year ‘B’ received Rs. 18,000 as profit out of total profit of Rs. 30,000, then find the value of ‘x’.
Ratio of profit share of ‘A’ and ‘B’ = (1600 × 12):(9 × x) Profit share of ‘A’ = 30000 – 18000 = Rs. 12,000 ATQ; {9x/(12 × 1600)} = (18000/12000) => 9x = 28800 So, x = 3200
