Hi,

It takes 20 men to build a building for 60 days. Assuming that all men work at this rate, 

how many green%28X%29 men will be needed to build the same building in 15 days?

N%5B1%5D+%2A+T%5B1%5D+%2A+W%5B1%5D+=N%5B2%5D%2AT%5B2%5D%2AW%5B2%5D

  60%2A20days%2A1+=+X%2A15days%2A1

      1200 = 15X

        80men = X
