Note: This question paper contains two parts A and B.
i) Part- A for 10 marks, ii) Part - B for 50 marks.
Part-A is a compulsory question which consists of ten sub-questions from all units
carrying equal marks.
H
Part-B consists of ten questions (numbered from 2 to 11) carrying 10 marks
each. From each unit, there are two questions and the student should answer one
of them. Hence, the student should answer five questions from Part-B.
