(1) Car A finished the trip with one 20 gallon tank of gas while Car B needed to refill its 20 gallon tank to finish the trip.
This information is clearly enough to deduce that Car A has not used more gasoline that Car B(Sufficient)

(2) For the entire distance, car A traveled 25 miles per gallon of gasoline and car B traveled 19 miles per gallon of gasoline.
Knowing the mileage of the cars, it is clearly deducible that the car B would have used more gasoline than Car A. Car A will consume 16 gallons of gasoline where as
Car B will consume around 21 gallons.(Sufficient)
.
Since both the options are individually enough to answer the question, the answer choice is Option D

(1) Car A finished the trip with one 20 gallon tank of gas while Car B needed to refill its 20 gallon tank to finish the trip.
(2) For the entire distance, car A traveled 25 miles per gallon of gasoline and car B traveled 19 miles per gallon of gasoline.


We are given that both cars A and B traveled 400 miles and started with the same amount of gas in each of their tanks. We need to determine whether car A used more gas than car B did.

Statement One Alone:

Car A finished the trip with one 20-gallon tank of gas, while car B needed to refill its 20-gallon tank to finish the trip.

This means car B used more gas than car A to complete the trip, i.e. car A did not use more gas than car B did. Statement one alone is sufficient to answer the question.

Statement Two Alone:

For the entire distance, car A traveled 25 miles per gallon of gasoline and car B traveled 19 miles per gallon of gasoline.

Since car B has a lesser rate of mpg than car A does, car B used more gas during the 400-mile trip than car A did. Statement two alone is sufficient to answer the question.

Answer: D
