Question

There are 500 children in a school. For a P.T. drill they have to stand
manner that the number of rows is equal to number of columns. How man
would be left out in this arrangement.​

Answer 1

Answer

16

Step-by-step explanation:

Let the number of rows be x

We are given that the number of rows is equal to number of columns

So, x²=500

x=√500

x=22.36

So, Number of rows = 22 = number of columns

So, Number of students in arrangement =- 22*22=484

No. of children would be left out in this arrangement = 500 - 484 = 16

Hence 16 children would be left out in this arrangement

Answer 2

Answer:

Let the number of rows be x

We are given that the number of rows is equal to number of columns

So, x \times x = 500x×x=500

So, Number of rows = 22 = number of columns

So, Number of students in arrangement =- 22*22=484

No. of children would be left out in this arrangement = 500 - 484 = 16

Therefore, 16 children would be left out in this arrangement
