If 8 carpenters can make 50 chairs in 10 days, how many carpenters are needed to make 75 chairs in 10 days? Let's answer step by step:
The carpenters need to produce 75 / 50 = 1.5 times as many chairs in the same number of days. It will require 1.5 times as many carpenters to produce the extra chairs, so 8 * 1.5 = 12 carpenters will be required. The answer: 12.
