Answer:
work done by A and B together in 1 day =
1/10
work done by B and C together in 1 day =
1/15
work done by A and C together in 1 day =
1/12
2(work done by A, B and C) in 1 day
= (1/10+ 1/15+ 1/12)
= 6+4+5/60
= 15/60= 1/4 =
work done by A, B and C=1/4*2 = 1/8 Time taken by them all together = 8 days
