Question
‘A’ started a business by investing Rs. 1000. Three
months later, ‘B’ joined by investing Rs. ‘x’. If at the end of the year ‘B’ received Rs. 12,000 as profit out of total profit of Rs. 20,000, then find the value of ‘x’.Solution
Ratio of profit share of ‘A’ and ‘B’ = (1000 × 12):(9 × x) Profit share of ‘A’ = 20000 – 12000 = Rs. 8,000 ATQ; {9x/(12 × 1000)} = (12000/8000) => 9x = 18000 So, x = 2000
