should be D 12x5 (Mon-Fri 8am to 8PM) = 60 hours only four hours on Wednesday from 4 pm to 8 pm so , 2 + 4 + 3 + 3 = 12 Hours (48 / 60 )* 100 = 80 %

12x5 (Mon-Fri 8am to 8PM) = 60 2 + 5 + 3 + 3 = 13 (No Sat) 60-13=47 47/60*100 = 78,3%

Note : ONLY 8AM-8PM ( Mon to Friday) ==>12hours x 5days = 60 Hours So we will take: ✑ Monday = 10 AM to 12 PM ( 2 hours) ✑ Wednesday = 4 PM to 9 PM ( 4 hours) --> 4PM till 8PM ONLY ✑ Thursday = 4 PM to 7 PM ( 3 hours) ✑ Friday = 3 PM to 6 PM ( 3 hours) ✑ Saturday = 9 AM to 1 PM ( INVALID as this is Saturday) Calculation : --> 2+4+3+3 = 12 --> 60-12 = 48 --> 48/60 x 100% Final Answer : 80%

12x5 (Mon-Fri 8am to 8PM) = 60 hours only four hours on Wednesday from 4 pm to 8 pm so , 2 + 4 + 3 + 3 = 12 Hours (48 / 60 )* 100 = 80 %

The correct answer is D: 80% - port work from 8 PM to 8 AM so missing in Wednesday will be only 4 hours not 5 - 2 + 4 + 3 + 3 = 12 hours - 60 - 12 = 48 - (48/60) * 100 = 80%

SHOULD BE 78.3% WHAT A MESS!!

SHOULD BE C - 78.3% 12x5 (Mon-Fri 8am to 8PM) = 60 horas totales de servicio 2 + 5 + 3 + 3 = 13 en falla con 4 fallas (Sat no se cuenta) Tiempo en falla = (13*100)/60= 21.66% % Tiempo disponible= 100% - Tiempo en falla = 78.33%
