Question
If Worker E works alone for 15 days, how many units of
the project will remain incomplete after this period? Direction: Five workers β A, B, C, D, and E β are working on a construction project to complete 500 units of work. Each worker works different numbers of hours per day and has varying work efficiencies, which are calculated as the number of units completed per hour. The following table shows the daily working hours and the efficiency (units per hour) for each worker:Solution
Total work done by E in 15 days = 15 Γ 9 Γ 1.8 = 243 units. Remaining work = 500 - 243 = 257 units.
