There are already 18 arcs in the graph. It doesn't say how many men V,W,X,Y, or Z dance with but the maximum could be 8 addition men each (as only 2 of the men are accounted for so far in the question). Thus the maximum is the 18 already included + 8x5 more, so 58

Me too! Could not get my head around it! Did anyone else's critical path look strange? What were your critical activities?

Thats what i thought it was sayin x + y + z = 20 but x had to be at least 20 and y and z had to be at least 24???
And fingers crossed😂the rest of the paper was decent but the LP q threw me off

Hopefully someone puts on a picture of the exam paper like they normally do for maths!

I have just come out of that exam; it couldn't have gone worse. I did not finish, and was unable to answer most questions with confidence. I hope I am not the only one that feels that way.
