  • Q43.Directions: Answer the question based on the following information.
    Economists are assigned a number called Keynes number (named after the famous Economist, John Maynard Keynes). Only John Maynard Keynes himself has a Keynes number of zero. Any Economist who has written a research paper with Keynes has a Keynes number of 1. For other, Economists the calculation of his/her Keynes number is illustrated below
    Suppose that an Economist, X has co-authored papers with several other Economists. From among them, Economists Y has the smallest Keynes number. Let the Keynes s number of Y be y. Then, X has a Keynes number of y + 1. Hence, any Economists with no co-authorship chain connected to Keynes have a Keynes number of infinity.
    In a seven day long mini-conference organized in memory of John Maynard Keynes, a close group of eight mathematicians, call them A, B, C, D, E, F, G and H, discussed some research problems. At the beginning of the conference, A was the only participant who had an infinite Keynes number. Nobody had a Keynes number less than that of F.
    On the third day of the conference F co-authored a paper jointly with A and C. This reduced the average Keynes number of the group of eight mathematicians to 3. The Keynes number of B, D, E, G and H remained unchanged with the writing of this paper. Further, no other co-authorship among any three members would have reduced the average Keynes number of the group of eight to as low as 3.
    At the end of the third day, five members of this group had identical Keynes number while the other three had Keynes numbers distinct from each other. On the fifth day, E co-authored a paper with F which reduced the group's average Keynes number by 0.5. The Keynes numbers of remaining six were unchanged with the writing of this paper. No other paper was written during the conference.

    How many participants in the conference did not change their Keynes number during the conference?

    Two traders, Anamika and Deepak, were involved in the buying and selling of IDBI shares over five trading days.

    If on any day, the closing price was above Rs 110, then Deepak sold 10 shares of IDBI, while if it was below Rs 90, he bought 10 shares, all at the closing price.

    If Anamika sold 10 shares of IDBI on three consecutive days, while Deepak sold 10 shares only once during the five days, what was the price of IDBI at the end of day3?
