. A alone can do a piece of work in 6 days and B alone can do it in 8 days. In how many days will the work be completed if they both worked together?​

Answer 1

Answer:

A alone can do a piece of work in =6 days

A can do the work in 1 day =1/6 of the work

B can do the same work in 1 day =1/8 of the work

They both together will do the work in one day =1/6+1/8

=L.C.M=24

=4+3/24

=7/24 of the work

. ' . They both together will complete the work in =24/7=3 3/7 days
