Noticed some possible mistakes in the numerical test #2:
- Spur gears produced - Isn’t the max. difference of pieces per hour = 3*(3+3+5+10+14) - 3*(0+0+0+5+7) = 69? You assume that more than one operator can use one machine at the time.
- Regarding the speed limits and the transportation companies - Shouldn’t be the answer 21:26:30?
And could anyone please explain the wage bill change in test #1?
