Question
βAβ and βBβ started a business by investing Rs.
βyβ and Rs. βy + 300β, respectively. If 10 months later the ratio of profit shares of βAβ and βBβ was 3:4, respectively, then find the amount (initially) invested by βBβ.Solution
ATQ; [(10 Γ y)/{(y + 300) Γ 10}] = (3/4) Or, (10y Γ 4) = 30 Γ (y + 300) Or, 40y = 30y + 9000 Or, 10y = 9000 So, y = 900 So, initial investment made by βBβ = 900 + 300 = Rs. 1,200
