Thirty-Six Men Can Finish Building A House In 120 Days. If A Third Of The Original Number Of Men Were Added, How Many Days Would Take The Whole Group
Thirty-six men can finish building a house in 120 days. If a third of the original number of men were added, how many days would take the whole group to finish the same house? I need an explanation please.
Answer: 90 days
Step-by-step explanation: That question involves inverse proportionality. One-third of 36 is 12. Add that you get 48. 36 * 120 = 4320
4320 divided by 48 is 90.
