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?

Answer

a) $320

b) $340

c) $360

d) $380

e) $400**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.

A man can finish the work in 12 days

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.

Amount to be paid to two men for 6 days = 2 * 6 * $150 = $1800

Amount to be paid to three women for 6 days = 3 * 8 * 6 * $10 = $ 1440

Amount of money saved...
