A piece of work can be completed by 45 men in 90 days if only 30 men are available, how many days will it take to complete the s
andrew-mc [135]

Answer:

  135 days

Step-by-step explanation:

Often, we measure work in man·days. This piece of work requires ...

  (45 man)·(90 days) = 4050 man·days

When there are only 30 men, the number of days required can be found by dividing this work by the number of men:

  4050 man·days/(30 man) = 135 days

_____

Another approach is to realize the time is inversely proportional to the number of men. If the number of men is 30/45 = 2/3 the original, then the time will be 3/2 the original, or ...

  (3/2)·90 days = 135 days.
