B275
C310
D280
Correct answer: (A) 300
Explanation
The average number of female athletes from country B is 300, so the answer is 300.
The female athletes from country B are counted for each of the six years.
Their numbers are 210, 310, 240, 420, 260 and 360.
These add up to 1800 in all.
The average is this total divided by the six years.
So it is 1800 divided by 6.
That equals 300, so the answer is 300.
