A car manufacturer organized a test drive of two of its prototypes. Each driver tested both prototypes and was asked if he or she liked the prototype. If a driver did not like a prototype, he or she was asked if the prototype's performance was the main reason. A driver did not like a prototype because of its performance 180 itmes, whereas only half as often a driver did not like a prototype because of some other major reason. How many test drivers were there?

The information in the question stem tells us that we have a total of 270 dislikes among the drivers.
We need to find the total number of likes, and from that we can calculate the number of drivers.
Statement 1 : 120 people liked both protototypes.
we don't know how many people liked just 1 prototype
NOT SUFFICIENT
Statement 2: As many people liked neither prototype a liked both of them
NOT SUFFICIENT
Combining the statements together
we can see that 120 people liked neither (that's 240 dislikes in total) and 120 liked both, meaning that 30 (from the information in the question stem) people liked one prototype.
Answer Option C.
