Please help with a math problem
Please help with the following problem:
The forms design section of a city agency recommended that the sizes of forms used by the agency be limited to the sizes that can be cut with the least amount of waste from either 17" by 22" or 17"x 28" sheets. Of the following, the size that does NOT comply with this recommendation is:
A. 4.25 x 5.5
B. 3.75 x 4.25
C. 3.5 x 4.25
D. 4.25 x 2.75
I calculated the square inches of each sheet and divided by the square inches of the possible choices. I did not get the correct answer.
Please tell me how you arrived at your answer. Thanks in advance.

Hmmmm.... Is this a homework problem?

No, it's a problem out a book for a civil service exam. You get the answer key but no explanations.
Look at the lengths rather than the square area. 17 divides quite neatly by 4.25 which appears in all the answers, so you want to find one where the other value doesn't divide nicely into 22. The one with the largest remainder is the answer.
It's about cutting out cards so you just need to line them up so they fit best into the sheet you are cutting from.
Can't edit very well as I'm on my mobile and can't scroll up to the question to check the other values, but I think I remember that A and D had values that divided exactly into 22.
Hope this helps.

Ah, forgot the 28". C can be cut from that one with no waste.
