Dear aspirant !

Hope you are doing well ! Firstly there is a suggestion for you by me that you shouldn't focus on passing marks ,you should do hardwork for boards exam at least as these boards exam will decide your life further ,as these are very crucial exam so everyone should give their best ,now let's come to the point if you want to know just the passing marks then as we know 33% are required to pass any exam .As your exam is of 40 marks then you need to score 13 at least ,less than 13 will fail you. So 13 or more than 13 will pass you,again I am saying try to score maximum marks.Rest depend on you.
