Of the 3,000 cars manufactured in Factory Q last year, how many were still in operation at the end of the year?

(1) Of all of the cars manufactured in Factory Q, 60% were still in operation at the end of last year.
(2) A total of 48,000 cars manufactured in Factory Q were still in operation at the end of last year.

We need to find the number of cars manufactured in Factory Q last year that were still in operation by the end of the year.

Statement 1: This statement mentions all the cars manufactured in Factory Q, not just the ones manufactured last year. Using the percentage given, we cannot estimate the number manufactured last year that were still in operation at the end of the year. Insufficient.

Statement 2: This tells us the total number of cars ever manufactured by Factory Q that were in operation last year, but there is no way to find the number manufactured last year that were still in operation at the end of the year.

Combining both statements, we know the number of cars manufactured in Factory Q last year and the number of all cars manufactured by Factory Q that were in operation last year. However, using this, it is not possible to determine the number of cars manufactured in Factory Q last year that were still in operation by the end of the year.

Option (E).
