Here is the complete breakdown of NDA 1 2021 Mathematics question paper. All the topics were covered but there were some exceptions like none of the questions figured up from the binary section. Going through topic wise analysis of questions we can deduce that the Algebra and statistics topic covered highest ever count, i.e. 33 and 15 questions respectively out of 120 questions that’s nearly 27.5% and 12.5% of the paper.
