Answer:
A -> 9/4 days - 1 work
1 Day - 1/9/4 = 4/9 work
B -> 9 days - 1 work
1 day - 1/9 work
adding their work of 1 day we get :
4/9 + 1/9 = 5/9
so,
5/9 work - 1 day
1 work - 9/5 days
that's the answer :)
the answer is three days and I don't know how it is come
check if you can
no I checked in my school books answer sheet and your answer is wrong
what is the answer
it is 3 days

A one day work =4/9
B one day work=1/9
A+B one day work= 1+4/9
=5/9
A+B completed work in =1/(5/9)
