Question
P’s 5 days work is equal to Q’s 6 days work. If P
and Q together can complete the work in 25 days then how much time Q will take to complete 80% of the work?Solution
Ratio of efficiency of P and Q = 6:5 Let the efficiency of P and Q be 6x and 5x units per day respectively. Total work = 11x × 25 = 275x units Required time = (0.80 × 275x)/5x = 44 days
