If 8 carpenters can make 50 chairs in 10 days, how many carpenters are needed to make 75 chairs in 10 days?
Let's think step by step.
12
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.

.

Therefore, the answer is 12
