Explanation

Start by computing the sums of the average ratings using the table:

 Category A B C Convenience 5.1 8.0 4.3 Friendliness 5.0 5.5 5.4 Price 5.0 6.4 3.5 Promptness 6.5 6.9 4.1 Reliability 7.8 7.5 4.9 Total: 29.4 34.3 22.2

The airline with the least sum is C (22.2)

Now look at the pie graph to see how many travel agents ranked Airline C first. The bottom left quadrant of the circle has 20 agents rating CAB, meaning C was first, A was second and B was third. Above this, 2 agents rated CBA, meaning C was first, B was second, and A was third. So in all 22 agents (20 + 2) rated C first.

Now determine the fraction: 22 travel agents out of 100 total rated C first, so 22/100.

Can '11/50' be the answer, too?
I'm Korean, and it is common to reduce a fraction in Korea.
When I submit 11/50 as an answer, will ETS grade it as the wrong?

11/50 is also correct! You can reduce to lowest fractions in such questions.
