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