The total number of employees per year is found on pg. 10, with that, and seeing on pg. 11 the percentage of female workers in the company, it is easy to get the answer. Just multiply the number of employees by the percentage of male employees.
The answer was not correct. In page 26 of the 2020 Sustainability Report, the exact number is located, being 28487 male employees.
Arturo is right!
