Max. Marks: 17 Time: 20 minutes
i) ii) iii) iv)
This section consists of 17 part questions and all are to be answered. Write this Code No. in the Answerscript. Each question carries one mark. Do not copy down the part questions in your answerbook. Write only the answer in full against the proper number of the question and its part. The code number of your question paper is to be written in bold letters in the beginning of the answerscript. The use of scientific calculator is allowed. All notations are used in their usual meanings.
