Suppose there are two consumers, A and B, and two goods, X and Y. Consumer A views the two goods as perfect complements and has U=min(X,Y). Consumer B views the two goods as perfect substitutes and has U=X+Y. There are 20 units of good X and 10 units of good Y available. For each of the following allocations, state TRUE if the allocation is Pareto efficient, and FALSE if it is not.

i) Consumer A gets all of both goods.

ii) Consumer B gets all of both goods

iii) Consumer A gets 5 units of each good, and consumer B gets 15 units of good X and 5 units of good Y.
