Usually, 2 out of the 3 variants are the exact same thing with question numbers changed. But one of them is a totally different paper. So you should do all the papers that are different. You solve past papers to practice, and the more papers you have the more you can solve. So whenever you see variants, open them once and check if they are the same or different to the other variants, hence, solve each different one.
