** You are not allowed to leave the examination hall during the first 30 minutes and the last 15 minutes of the examination time.
** When you finish the examination, hand in this booklet and the bubble sheet to the invigilator.
Before you start :
** Check that this booklet has pages 1 through 21. Also check that the top of each page is marked with EEE 2015 01. Report any inconsistency to the invigilator.

Part I
** This part of the examination consists of 20 multiple-choice questions. Each question is followed by four possible answers, at least one of which is correct. If more than one choice is correct, choose only the `best one’. The `best answer’ is the one that implies (or includes) the other correct answer(s). Indicate your chosen best answer on the bubble- sheet by shading the appropriate bubble.
** For each question, you will get: 1 mark if you choose only the best answer; 0 mark if you choose none of the answers. However, if you choose something other than the best answer or multiple an- swers, you will get ??1=3 mark for that question.

There are two individuals, 1 and 2. Suppose, they are oered a lottery that gives Rs 160 or Rs 80 each with probability equal to 1/2. The alternative to the lottery is a xed amount of money given to the individual. Assume that individuals are expected utility maximizers. Suppose, individual
1 will prefer to get Rs 110 with certainty over the lottery. However, Individual
2 is happy receiving a sure sum of Rs 90 rather than facing the lottery. Which of the following statements is correct?
