Question
P’s 3 days work is equal to Q’s 4 days work. If P
and Q together can complete the work in 32 days then how much time Q will take to complete 75% of the work?Solution
Ratio of efficiency of P and Q = 4:3 Let the efficiency of P and Q be 4x and 3x units per day respectively. Total work = 7x × 32 = 224x units Required time = (0.75 × 224x)/3x = 56 days
