Question

A can complete work in 5 days B in 6 days and c in 12 days Together if they work how many days will they take​

Answer 1

Answer:

given, A completes s work in 5 days, B in 6 days and C in 12 days.

to find number of days taken to complete the work if they work together

A' s one day work is 1/5

B's one day work is 1/6

C's one day work is 1/12

therefore A,B and D's one day work if they work together is 1/5+1/6+1/12 = (12 + 10 + 5)/60

= 27/60

therefore together they take 60/27

or 2 and 6/27 days 2.2 days
