Explanation

Female athletes from B: 4.2, 6.2, 4.8, 8.4, 5.2, 7.2. Sum = 36.0 (hundreds). Average = 36/6 = 6 hundreds = 600.

AI explanation

Extract the number of female athletes from country B, which are 4.2, 6.2, 4.8, 8.4, 5.2 and 7.2 (in hundreds). The sum of these values is 36. Using the average formula, divide this total sum by the 6 years. This gives 6, and because the units are in hundreds, the average is 600.
