Answer 2

The number of students without SPC uniforms are 700.

Step-by-step explanation:

Given,

Total number of students of puthur high school = 784

Let the number of row = the number of column = x

To find, the number of students without SPC uniforms = ?

∴ $x\times x=784$

⇒ $x^{2} =784$

⇒ $x^{2} =28^{2}$

⇒ $x=28$

∴The number of row = The number of column = 28 stodents

The number of SPC students = 3 × 28 = 84

The number of students without SPC uniforms = Total number of students of puthur high school - The number of SPC students

= 784 - 84

= 700

Hence, the number of students without SPC uniforms are 700.
