A PT teacher arranges students into a solid square drill. After the arrangement, he finds that 24 students are left over. If the total number of students is 2140, how many students are in each row?

1. 44
2. 54
3. 46
4. 56

Correct answer: 46

Solution

If 24 students are left over, the number arranged in a square is 2140 - 24 = 2116. Since 2116 = 46^2, each row has 46 students.
