In an arena, each row has 199 seats. One day, 1990 students are coming to attend a soccer match. It is only known that at most 39 students are from the same school. If students from the same school must sit in the same row, determine the minimum number of rows that must be reserved for these students.

10 rows

Step-by-step explanation:

Given:

Seats on each row = 199.

Population of student attending = 1990.

no of students from same school = 39.

Therefore;

If the students from same school must seat in same row determine the number of rows that most be reserved for these students.

1. At most 39 students from same school

= total population of all students/ students from same school

= 1990 / 39

= 51 schools would be attending the event

2. No of students a row can accommodate

= Seats on each row / no of students from each school

= 199/39

= 5

3. No of rows to that most be reserved

= 51 / 5

= 10

So 10 rows must be reserved.
