Question
15 men can complete 3/5 part of a work in 8 days working
9 hours a day. How many women can complete rest of the work if they work for 6 hours a day for 10 days and efficiency of a man is four times the efficiency of a woman.Solution
Let number of women be W. We know that, (M1 × D1 × H1 × E1)/W1 = (M2 × D2 × H2 × E2)/W2 (15 × 8 × 9 × 4)/(3/5) = (W × 10 × 6 × 1)/(2/5) W = 48
