Question
Find the value of "w" if Armaan can complete a Sales
target in (w + 20) days, Malik can complete it in (w + 44) days, and when they work together, they can complete the entire target in 35 days.Solution
ATQ, 1/(w + 20) + 1/(w + 44) = 1/35 35(w + 20 + w + 44) = (w + 20)(w + 44) 70w + 2240 = w2 + 64w + 880 w2 – 6w – 1360 = 0 Solving above equation we get w = 40
