-- 1 man can do the job in 100 days.-- Each day, 1 man does 0.01 of the job.-- Each day, 10 men do 0.1 of the job.-- In 6 days, 10 men do 0.6 of the job.-- If 15 women work with the 10 men, they can all finish the job in the same 6 days.-- So the 15 women must do the remaining (1 - 0.6) = 0.4 of the job in 6 days.-- Each day, the 15 women do 0.4/6 of the job.-- Each day, each woman does 0.4/(6 x 15) of the job.-- So it would take 1 woman (6 x 15)/0.4 days to do the job.That's 225days.(Does this mean that women should earn 100/225 = 44.4% the hourly wage of men ? ?)
