Workers C and D work together for 10 days. Calculate how
many units they will complete in this period. Direction: Five workers – A, B, C, D, and E – 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 C in 10 days = 10 × 5 × 4 = 200 units. Total work done by D in 10 days = 10 × 7 × 2.5 = 175 units. Total work by C and D = 200 + 175 = 375 units.
