Out of 745 students, maximum are to be arranged in the school field for a P.T. display, such that the numbers of rows is equal to the number of columns. Find the number of rows if 16 students were left out after the arrangement.
Ans : Total number of students = 745
Students left after standing in arrangement = 16
No. of students who were to be arranged = 745 - 16 = 729
The number of rows = no. of students in each row
No. of rows = √729
