Question
P and Q can finish a job working
together in 24 days. P completes two-thirds of the task in 'd' days, and Q finishes the rest in 'd/4' days. Determine the value of 'd'.Solution
ATQ, Time taken by P to complete the task = d/(2/3) = (3/2)d days Time taken by Q to complete the task = (d/4)/(1/3) = (3d/4) days According to question, 2/3d + 4/3d = 1/24 (2 + 4)/3d = 1/24 2/d = 1/24 d = 2 × 24 = 48
