Question
P’s 2 days work is equal to Q’s 3 days work. If P
and Q together can complete the work in 30 days then how much time Q will take to complete 60% of the work?Solution
Ratio of efficiency of P and Q = 3:2 Let the efficiency of P and Q be 3x and 2x units per day respectively. Total work = 5x × 30 = 150x units Required time = (0.60 × 150x)/2x = 45 days
