The kitchen manager at an italian restaurant is deciding what assignments he should give to his two cooks, john and david. john can make 25 pizzas or 40 servings of pasta per hour and david can make 20 pizzas or 30 servings of pasta. which of the following should be the manager's choice?

The answer is: David should make pizza and John should make pasta.

Explanation:

John is more efficient at producing both pizza and pasta, but considering he can only make one at a time we calculate David´s productivity compared to John´s.

David is 80% as productive as John in making pizza, and only 75% as productive in making pasta.

David should be in charge of making pizza because his productivity is closest to John´s.
