Question
P’s 4 days work is equal to Q’s 5 days work. If P
and Q together can complete the work in 20 days then how much time Q will take to complete 40% of the work?Solution
Ratio of efficiency of P and Q = 5:4 Let the efficiency of P and Q be 5x and 4x units per day respectively. Total work = 9x × 20 = 180x units Required time = (0.40 × 180x)/4x = 18 days
