Question

A,B and C can do a job alone in 6, 12 and 24
days respectively. In what time will they do it​

Answer 1

Answer:

24/7 days

Step-by-step explanation:

A alone takes 6 days to complete the job

So, in one day A does 1/6 of the job

Similarly, in one day B and C does 1/12 and 1/24 of the job respectively.

Now in one day they together does 1/6+1/12+1/24=7/24 of the job.

So the total time taken to complete the job is 24/7

Hope this helps.
