Explanation

The question asks for the same minimum number of students across shifts. The morning shift has 20 students in one group, and evening shifts have 16 students each. The least common multiple (LCM) of 20 and 16 is 80, meaning 80 students in morning (4 groups of 20) and 80 in evening (5 groups of 16).
