All trainees in a certain aviator training program must take both a written test and a flight test. If 70 percent of the trainees passed the written test, and 80 percent of the trainees passed the flight test, what percent of the trainees passed both tests?

(1) 10 percent of the trainees did not pass either test.
(2) 20 percent of the trainees passed only the flight test.


Kudos for a correct solution.

Let the number of employees be 100

- 70 percent of the trainees passed the written test
- 80 percent of the trainees passed the flight test
Let x be the number of employees passed both tests

Statement 1 : 10 percent of the trainees did not pass either test.
100 = 70 + 80 - x +10
x= 60. Sufficient

Statement 2 : 20 percent of the trainees passed only the flight test.
Therefore, trainees passed both flight and written tests = 80 - 20 = 60. Sufficient

Hence D) should be the answer
