Question

One fourth of a group of people claim that they are creative, twice the square root of the group claim to be caring and the remaining 84 claim they are optimistic.

Answer 1

Let total Number of People in the group be X

Thus
According to Question

Number of Creative People = A = 1/4 X
Number of Caring People = B = 2 root X
Number of Optimistic People = C = 84
Thus
Clearly
Total Number of People in Group = A + B + C
                   X            =   1/4 X +  2 root X + 84
3/4 X - 2 root X = 84
3X - 8 rootX = 336
x = 144
Thus Total Number of People in Group = 144
