women can complete it in 5 days. 8 men start working on the job & after working for 3 days, all of them stopped working. How many women should be put on the job to complete the remaining work in 4 days?Solution
One day work of a man = 1/(15 ×5) = 1/75 So, 3 days work of 8 men = 1/75 ×8 ×3 = 8/25 Remaining work = 1 - 8/25 = 17/25 One day work of a woman = 1/(20 ×5) = 1/100 According to the question Remaining work should be completed in 4 days Let the total number of women required to complete the remaining work in 4 days = x 4 days work of x women = 1/100 ×4 ×x = 17/25 x=17
