I think there is something wrong with the question....K can be 1 or 1000.

It takes X and Y 3/2 hours to produce k bottles, so (3/2)/k per bottle. For 12 bottles, 12(3/2)(1/k)

Machine X - K/6 bottles in 1 hour
Machine Y - K/2 bottles in 1 hour

Together, 2K/3 bottles in 1 hour

To produce 12 bottles, both will take 18/K hours

Is there a problem with the question? The number of hours depends on the value of K
