A factory employs 28 workers to complete an order in 18 days by working 9 hours each day. How many more workers are required to complete the same order in 14 days by working 6 hours daily?

ATQ, In work and time questions, total work depends on the number of workers, number of days and working hours per day. Total work = Workers × Days × Hours per day In the first case: Number of workers = 28 Number of days = 18 Working hours per day = 9 So, total work = 28 × 18 × 9 = 4536 worker-hours In the second case, the same work has to be completed in 14 days by working 6 hours per day. Let the required number of workers be X. So, X × 14 × 6 = 4536 X × 84 = 4536 X = 4536 ÷ 84 = 54 So, 54 workers are required to complete the work in the given time. Already available workers = 28 More workers required = 54 − 28 = 26
