Answer 2

The minimum number of rows required = 23

Given:

A school hall has to be constructed in such a way that each row has 28 seats

Number students that should be seated at a time = 650

To find:

Minimum number of rows that students can be seated

Solution:

Given number of students = 650

Number students can be seated in a row = 28

Let us assume that number of rows = x

According to given data,

Number of students can be seated in x seats = 28x

As we know total number students should be seated = 650

⇒ 28x = 650

⇒ x = 650/28

⇒ x = 23.23

Therefore,

The minimum number of rows required = 23
