2 SAMPLE QESTION PAPER Class- XI Sub- MATHEMATICS Time : Hrs. Maximum Marks : 00 General Instructions :. All the questions are compulsory.. The question paper consists of 0 questions divided into four sections A, B, C, D. Section A comprises of 6 questions of one mark each. Section B comprises of 6 questions of two marks each. Section C comprises of questions of four marks each and section D comprises of 5 questions of six marks each.. This set of model questions is not unique in character. Several such set of model questions can be framed. Teachers are requested to frame model questions of this kind for their Students. Section- A Question numbers to 6 carry mark each. For each question four options are provided out of which only one is correct. Write the correct option..
