Answer 1

Answer:

Step-by-step explanation:

A,B,C 1 hour work is=1/8+1/10+12= 37/120

A,B,C work together for 2 hours, so,A,B,C 2 hours work is: (37/120)*2=37/60

remaining work=1-37/60=23/60 (23/60 work is done by B and C together)

B,C 1 hour work is= 1/10+1/12=11/60

23/60 hours work done by B,C= (11/60)* (60/23)=11/23

so... ans is: 2(1/11)
