Two painters paint

These more advanced challenges are definitely logic puzzles for adults. But while they are intricate, don’t feel bad taking as much time as you need to work out your logic.

If two painters can complete two rooms in two hours, how many painters would it take to do 18 rooms in 6 hours?

ready for the answer?

It would take six painters. Two painters can complete two rooms in 2 hours, so four man hours for two rooms which is two man hours per room.
So 18 rooms requires 2 X18 = 36 man hours.
36 man hours for six hours means 36 / 6 = 6 men are working 6 hours to paint 18 rooms.
