  1. Two firms F1 and F2 make colour and black and white television sets. F1 can make either 300 colour sets in a month or an equal number of black and white sets, and make a profit of Rs, 2000 per colour sets and 1500 per black and white set.

Each month there is a market of 300 colour sets and 600 black and white sets and the manufacturers would share market in the proportion in which they manufacture a particular type of sets.
    Write the payoff matrix of F1 and F2 per month. Obtain F1 and F2's optimal strategies and the value of the game. [10]
