I need to have four different question papers in which the order of the above questions only changed and i need to give the answer for the respective question paper in a separate sheet. so kindly help me to prepare those question papers from this. That i need to prepare another question paper by shuffling the questions and i need to give the answer respectively. How should i do?

one more question ##

If i want to shuffle the question to prepare four different questions papers having same questions but with the different question numbers what should i do…??

that is i need to mark the question paper given above as Code A. and i need to print another question paper which marked as Code-B and in this question paper the first question code-A should be in question number 5 and similarly others also should have different positions…

thank you for your help in advance…

I incorporated this answer to solve your problem. After you write your four choices, put the correct choice (a, b, c, etc.) in braces as a fifth choice.
