Question 1002889
12 men complete the 2400 square meter ploughing work in 10 days. how many men are required to complete 3600 square meter ploughing work in 18 days?
------------------
2400 sq m takes 12*10 = 120 man-days
--> 1 man-day = 20 sq meters
---------------
3600/20 = 180 man-days
180 man-days/18 days = 10 men
