Answer:
6
Step-by-step explanation:
Data provided as per the question below:-
Number of students = 4025
Lockers = 805
The calculation of  the largest number of students who must necessarily share a locker is shown below:-
Largest number of students = ((Number of students - 1) Ă· Lockers) + 1
= ((4026 - 1) Ă· 805) + 1
= (4025 Ă· 805) + 1
= 5 + 1
= 6
