If 8 carpenters can make 50 chairs in 10 days, how many carpenters are needed to make 75 chairs in 10 days?
The carpenters need to produce 75 / 50 = <<75/50=1.5>>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 = <<8*1.5=12>>12 carpenters will be required.
