Does the certification which we get after we clear exam show the percentage as well ?
Does percentage matters a lot or is it good to go if we just clear the exam? Having higher percentage, does it add more value or is it just same as the one cleared the exam with just over passing criteria?
The certification badge does not show your score. Whether you pass with 70% or 100%, they look the same. I would say as long as you pass, you're fine. I would never ask to see a candidates score, although I'm sure you can find one employer who might.
Having taken all of the exams of the years, I would say the scores don't really matter. First off, they like to include beta/test questions that are unscored in your exam. I've confirmed this first hand with exam writers. So, you may have a question that makes no sense or contains an error, but is unscored.
