a contractor got a contract to build a building in 30 days and employed 20 men to do the work. only 1/4 work was completed in 10 days. how many more men be employed so that the work be completed in the specified time?

Find the number of man-hrs to complete 1/4 of the job

20 * 10 = 200 man-days

therefore

3 * 200 = 600 man-days required to complete the job (For a total of 800 man-days)

Let m, = no. of additional men required to complete the job in the remaining 20 days

20(m + 20) = 600

20m + 400 = 600

20m = 600 - 400

20m = 200

m = 200/20

m = 10 additional men required to finish the job in the required 30 days

Hope I got it right
