Austin and Blake can finish a piece of work in 18 days; Blake and Connor in 24 days while Connor and Austin in 36 days. In how many days will Austin, Blake and Connor finish it, working together? In how many days will each of them finish it, working alone? ​

Answer 1

Answer:

Austin and Blake can do in 1 day 1/18 part of work

Blake and Connor can do in 1 day 1/24 part of wor

Connor and Austin can do in 1 day 1/36 part of work

Together they can do in 1 day = 1/18+1/24+1/36=1/8 part of work

So, 2(Austin +Conner+ Blake)= 2(1/8)

Austin+ Conner+Blake)= 1/4

So, they together can do whole work in 4 days(Ans)
