A man working for 8 hours a day can complete a job in 12 days. He is paid a sum of $150 per day. Three women work as efficiently as two men, but are paid a sum of $10 per hour. A contractor needs to finish the job in 6 days. He has to decide between employing men or women. How much money will he save, if he employs women to do the job instead of men?
Solution: The trick to solve Work related questions is to try and equate the amount of work done by the two set of people, to arrive at a common point for the duration of work to be completed.
Therefore, two men can finish the same piece of work in 6 days.
Three women work as efficiently as two men, thus, three women can complete the piece of work in 6 days.
