Question

One- fourth of a group of people claim that they are innovative , twice the squareroot of group claim to be protective and the remaining 84 claim they are realistic .
(a) Find the total number of people in group.
(b) which of values according to you is essential for development of a society?

Answer 1

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
