How do you use the words 'For Which' in an English sentence?

I am trying to learn about on which, at which, on which, etc"

But I'm stuck with "for which" mostly 

 A. The shaded region to the right of the break-even point represents quantities for which the company makes a profit. 

B. The shaded region to the right of the break-even point which represents quantities for the company makes a profit.

Is sentence B same as sentence A?

2nd example of for which:

A. the luncheon for which we bought the food will take place outside.

B. the luncheon which we bought the food for will take place outside. 

Is sentence B same as sentence A and are they both grammatically correct?

Thank you,

Just one more follow up question: we were taught not to end sentences in preposition. So is it possible to rearrange the first example B without have the sentence end in "for"?


Alexa T.

Yes, that would be sentence A in the first example, where you use "for which" and end on the word "profit." Ending on a preposition isn't necessarily grammatically incorrect, but it may be less formal. In academic writing, you'd want to go with the more formal sentence A.

excellent answer. Thank you!

Hello. Here is a bonus comment from me: The two examples given above about "the shaded region..." are both a bit awkward and wordy. The idea might be expressible like this, alternatively: The shaded region...represents quantities profitable to the company. Thank you
