.
Marp=12 repairs/10 minutes=1.2 repairs/min
Orti=10 repairs/8 minutes=0.8 repairs/min
Eddi=8 repairs/6 minutes=1.33 repairs/min
All three together=1.2 repairs/min+0.8 repairs/min+1.33 repairs/min=3.33 repairs/min
For 100 repairs: (100 repairs)/(3.33 repairs/minute)=30 minutes
ANSWER: It would take the three working together 30 minutes to make 100 repairs.
