Answer 1

Answer:

1) 5 day.

2) 5/ 3 day.

Step-by-step explanation:

whole work = 1 part

A can complet it in 40 days.

B " " " 60. "

Now,

A can Do it 40 day = 1. the whole work.

" " " 1 " = 1/ 40 part of the " "

B can Do it 60 day = 1. the whole work.

" " " " 1. " = 1/60 part of the ""

A & B together will complete the work = ( 1/40 +1/60) = 5/6 part of the work in one day.

Extra work = ( 1 - 5/6)

= 1/6.

so now,

5/6 part together they com. in = 1 day.

1. " " " " " = 6/5 "

1/6. " " " " " = 5 day.

2) whole work they com. together in 5 day.

1/3 of the work " " " " " = 5/3 days.

I hope it's helpful.
