Instructions
Read the following instructions carefully :
(1) This question paper contains MCQ and numerical type questions divided into two sections:
(i) Section I – Question number 01 to 10 (10 Questions) will carry one mark each.
(ii)Section II – Question number 11 to 30 (20 Questions) will carry two mark each.
(2) Answer all the questions.
(3) Question must be answered on special machine gradable Objective Response Sheet (ORS) by darkening the appropriate bubble (marked A, B, C, D) using black ink ball pen against the question number on the ORS. Each question has only one correct answer.
(4) Wrong answer carries negative marks. For one mark, there is one-third negative mark. For, two mark two-third negative mark. No negative marking for numerical type questions.
(5) More than one answer bubbled against the question will be deemed as an incorrect response.
(6) Write your registration number and other details at the specified locations on the ORS.
(7) Calculator is allowed in the examination hall but the programmable calculator is not permitted.
