Answer:
E) y / ( x + y )
Step-by-step explanation:
Machine A need x hours to do the job
Then in one our machine A do 1/x of the job
Machine B need y hours to do the job
Then in one hour machine B do 1/y of the job
Then the two machines working together in one our time will make:
1/x + 1/ y = ( y + x ) xy
And the fraction of the job B does not need to do, since it was done by machine A is
( 1/x ) / (y + x ) / xy = y / ( x + y )
