Let the Total number of people be X
Thus According to Question
Innovative People = I = 1/4 of X
= X/4
Protective People = P = 2 root X
And
Realistic People = R = 84
So Clearly
X = P + I + R
X = X/4 + 2 root X + 84
3X/4 - 84 = 2 root X
Squaring both sides
9 X^2 + 112896 - 2016X = 64X
9X^2 - 2080 X = - 112896
9X - 2080 = - 112896
Thus According to Question
Innovative People = I = 1/4 of X
= X/4
Protective People = P = 2 root X
And
Realistic People = R = 84
So Clearly
X = P + I + R
X = X/4 + 2 root X + 84
3X/4 - 84 = 2 root X
Squaring both sides
9 X^2 + 112896 - 2016X = 64X
9X^2 - 2080 X = - 112896
9X - 2080 = - 112896
