The least number of students in the school is 90.
Given data :
All the students of that school can stand in the rows of 5 students or 9 students or 10 students in the each row.
- Now,we have to calculate the least number of students in that school.
- We have to calculate the LCM or Least Common Multiple of the number of students given in the row arrangements,to get the least number of students that can be arranged in the given row arrangements.
- So,the LCM of 5,9,10 is 90.
- So,the least possible number of students in that school is 90.
[10 rows of 9 students/9 rows of 10 students / 18 rows of 5 students]
