ReplyDeleteToo easy. It takes 2 hours for 1 worker to paint 1 wall. In 6 hours therefore 1 worker can paint 3 walls, hence you need 6 workers to paint 18 walls.

ReplyDelete2 walls 2 hours two people

ReplyDelete18 6 hours 6 people

they dont need to paint the wall,it is allready painted:P

ReplyDeleteIts 3 workers. Because 1 worker can paint one wall in 1 hr. So 3 workers can paint 18 walls in 6 hrs.

ReplyDelete6 is not the right answer.

ya its 6 workers. I overlooked the Q in the first time.. -)

ReplyDeleteLogic:

ReplyDelete6 workers.

So 2 workers paints 1 wall in 1 hour => in 6 hours they will complete 6 walls which is 3 times less than 18 =>

for painting 18 walls in 6 hours needs 6 workers.

3 workers
