Solution

The correct option is C 3
To find the number of rows with 6 chairs in a row we need to find all the factors of 18.
Total number of chairs =18
Chairs in a single row = 6
Factors of 18 = 1, 2, 3, 6, 9, 18
18 can be represented as:
1 x 18 , 2 x 9, 3 x 6
So, for 6 chairs in a row 3 such rows will be there in the classroom.
