Answer:
4480 employees
Explanation:
Total number of staffs = 6400 employees
If after the holiday they will decrease their staff bye 30%, the amount of staffs decreased = 30% of 6400
= 30/100 * 6400
= 1920employees.
Amount of staffs that they will have after the holiday = Total staffs - decrement
Amount of staffs that they will have after the holiday = 6400 - 1920
= 4480employees
