Question

Did different sets of questions paper have different questions?

Answer 1

It actually depends which organisation set the paper.

If you're talking about a school question paper, then I have observed that generally only one or two questions differ, and the rest have their orders interchanged.

Answer 2

This is highly common that the sets given out in the same question paper will have different questions in them. However; in certain cases, the questions can be twisted and asked where the answer for certain questions will be the same. A set contains multiple questions, and at the time it is possible for questions with the same resemblance in different sets of the same paper.
