Answer to Question 1

C

Questions 95 to 97: In the Banana Republic there are two producers of PCs, referred to as Pac and Bell. Assume that there are no PC imports. The market shares for these two producers are 70 for Pac and 30 for Bell. One executive at Bell proposes a longer warranty period (similar to one given by auto makers) to be offered at a slight extra cost as a plan to increase market share. A market research company appointed by Bell conducts a census of PC owners on their opinion of this warranty proposal. Among owners of a PC made by Pac, 50 like the proposal, 30 are indifferent to it, while the remaining owners oppose it. Among owners of a PC made by Bell, 70 like the proposal, 20 are indifferent to it, and the remaining owners oppose it.
