General Instructions

All questions are compulsory.

The question paper consists of 34 questions divided into four sections A, B, CandD.

Section Acontains 10 questions of 1 mark each, which are multiple choice type questions, Section B contains 8 questions of 2 marks each, Section C contains 10 questions of 3 marks each, Section D contains 6 questions of 4 marks each.

There is no overall choice in the paper. However, internal choice is provided in one question of 2 marks. 3 questions of 3 marks and two questions of 4 marks.
5. Use of calculators is not permitted
