An English company based on a support project has 509 male and 509 female workers. The average productivity of all employees is 59 calls/day. If a male worker receives 59 calls/day, how many calls per day will be received by a female employee?
59
Total calls per day by all employees = (509 + 509) × 59 = 1018 × 59.
Calls by the male workers = 509 × 59.
Calls by the female workers = 1018 × 59 - 509 × 59 = 509 × 59.
So each female worker receives (509 × 59) ÷ 509 = 59 calls per day.
Hence, 59.
