Question

one fourth of a group of people claim that they are inovative , twice the square root of the group claim to be protective and the remaining 84 claim they are realistic. Find the total number of people in the group?

Answer 1

let total are x
=> x/4 + 2√x +84 = x
=> 2√x = 3x/4 -84
square both side and solve the quadratic equation to get x

Answer 2

Answer:

144

Step-by-step explanation:

Let the total number of people be x

One fourth of a group of people claim that they are inovative

No. of Innovative people = $\frac{x}{4}$

Protective = $2\sqrt{x}$

Remaining =  $x-(\frac{x}{4}+2\sqrt{x})$

We are given that Remaining are 84

$x-(\frac{x}{4}+2\sqrt{x})=84$

$x=144$

Hence the total number of people in the group are 144
