Figure 1 depicts the percentage of the total number of male and female athletes from the given five countries: Australia, Brazil, Canada, China, and Italy who participated in the Tokyo Olympics in the year 021.
The total number of athletes who participated from the given five countries is 32400
In Figure 2, the percentage of the number of female athletes from the same five countries who participated in the Tokyo Olympics in the year 2021 are given as under:
If the average number of male athletes from all the given five countries 4000, then what was the average number of female athletes from Italy and Canada?
It is given that the total number of athletes who participated from the given five countries is 32400.
From figure 1, we can easily find the total number of athletes for each of the five countries.
Let the number of total female athletes from these five countries be 100x. Then we will get this table:
In the question, it's given that the average number of male athletes from all the given five countries 4000, which implies the total number of male athletes = (4000*5) = 20000
Hence, the number of total female athletes from these five countries = (32400 - 20000) = 12400
=> 100x = 12400 => x = 124
the average number of female athletes from Italy and Canada is (25x+14x)/2 = 19.5x =19.5 * 124 = 2418
The correct option is D
