The repair/reboot time needs to be reduced by 600 hours so as to increase availability time by 5%.

Step-by-step explanation:

To increase availability by 5%, the amount of hours of availability is multiplied 105%.

therefore 1.05 * 12000 = 12600 hours

Therefore the repair/reboot time needs to be reduced by 600 hours.
