Question
βPβ and βQβ invested Rs. βxβ and Rs. (x +
3000) respectively for 10 months and 5 months. The profit earned by P and Q is in the ratio 4:3. What was the investment made by Q?Solution
According to the question, (x Γ 10) / ((x + 3000) Γ 5) = 4 / 3 Or, 3 Γ 10x = 4 Γ 5(x + 3000) Or, 30x = 20x + 60000 Or, 10x = 60000 Or, x = Rs. 6000 Therefore, investment made by Q = (x + 3000) = Rs. 9,000
