Question

in a school function 968 student were made sit in the hall such that the number of rows is equal to the number of student in each row find the number of rows if 7 students were left after the arrangement​

Answer 1

Step-by-step explanation:

Total no. of students=968

Students left out =7

Students = 968-7

=961

Let the no. of rows be x

If rows and columns are equal then rows=columns=x

so

x × x =961

x^2=961

x=961^1/2

x=31

No. of rows and columns is 31
