Question
βPβ invested Rs. 5000 for (y + 3) months, while
βQβ invested Rs. 1500 more than βPβ for (y - 1) months, in a business. If profit received by βQβ out of total profit of Rs. 8400 is Rs. 3200, then find the value of βyβ.(Can calculate approx. value)Solution
ATQ, Ratio of profit received by βPβ and βQβ = {5000 Γ (y + 3)}:{6500 Γ (y - 1)} = (8400 β 3200)/3200 Or, (5000y + 15000):(6500y - 6500) = 5200/3200 Or, (25y + 75)/(32.5y - 32.5) = 13/8 Or, 200y + 600 = 260y - 260 Or, 860 = 60y Or, y = 860/60 = 14.33 (approximately 14)
