Let x be the total number of persons.
Then, number of creative persons = x/4
Number of caring persons =2√x
and number of optimistic persons = 15
Thus, total number of persons =
x/4+ 2√x + 15
Now, by hypothesis, we have


Hence, the number of people in the group = 36
(i) Number of Creative persons = 9 persons
(ii) All of these values have their own importance. A person having these values will certainly contribute to the development of society. However, the level of importance given to each of them depends upon a person’s own attitude. Hence, any value with justification is correct.
