sir I am studying in semester 4 English honours.My question is if I write the question no. wrong in the short answer type so what will happened

If you have mentioned entirely wrong serial number to the answer you have written, then its dependent on the teacher how much he/she is considerate. If its a very strict teacher, then your answer may get strike out. If he/she is a considerate teacher, then you will get some marks (some marks will be deducted due to such misapprehension).

So you will get or not, is entirely dependent on the teacher who will be checking your copy. So hope for the best!
