If 6 labourers clear a farm in 15 days , working 12 hours a day, how long will 9 labourers take working 10 hours a day ?
Answer provided by our tutors
6 Workers x 12 Hours each = 72 hours a day of work
72 hours of work x 15 days = 1080 total hours to clear a farm
9 workers x 10 hours each = 90 hours of work
1080 total hours to clear a farm / 90 hours of work a day = ***12 days***
