Question
P, Q, and R can complete a task in 2x, 25x, and x
days respectively when working alone. If they complete the task together in 19200 days, how many days would it take for only P and R to finish the task together?Solution
1/2x + 2/5x + 1/x = 19/200 On solving x = 20 days So, number of days taken by P and R to complete the work individually is 40 days and 20 days respectively. Number of days taken by P and R to complete the task while working together = 1/(1/40 + 1/20) = 40/3 days
