Question
P and Q individually can complete the work in 18 days
and 27 days respectively. If the time taken by R alone to complete the work is 1.25 times the time taken by P and Q together to complete the work, find the time taken by R to complete the work while working alone. MTSolution
Time taken by P and Q together to complete the work = (18 × 27)/ (18 + 27) = 10.8 days Time taken by R alone to complete the work = 1.25 × 10.8 = 13.5 days
