There are 480 male and female employees, and male employees account for 3 / 5 of the total number. If male employees are transferred, and male employees account for 9 / 20 of the total number, how many are transferred?

There are 480 male and female employees, and male employees account for 3 / 5 of the total number. If male employees are transferred, and male employees account for 9 / 20 of the total number, how many are transferred?

Female workers remain unchanged
There are 480 female workers (1-3 / 5) = 192
So later, the total number of people was 192 (1-9 / 20) ≈ 349 (not an integer)
So 480-349 = 131
Have a good time
