Solution

let the number of rows be x and number of students in one row be y.

therefore total number of students = xy.

if one student is extra in a row , there will be 2 rows less.

the number of students in 1 row = y+1. and the number of rows = x-2.

thus the number of students in the class = xy = 12*5 = 60
