A soap factory makes 600 cartons in 9 days with the help of 20 machines. How many cartons can be made in 12 days with the help of 18 machines?
Explanation
600 cartons / 9 days = 66.67 cartons/day (20 machines)
66.67 / 20 = 3.33 cartons/day/machine
18 machines * 3.33 = 60 cartons/day
60 * 12 = 720 cartons
