Answer:
9
Step-by-step explanation:
Let the total number of persons in the group be 'x'.
(i) Punctual = √x
(ii) Hardworking = 3.
(iii) Disciplined = (x/3).
Now,
According to the given condition,
⇒ (x/3) + √x + 3 = x
⇒ 2x + 3√x - 27 = 0
Let √x = y, then x = y²
⇒ 2y² + 3y - 27 = 0
⇒ 2y² + 9y - 6y + 27 = 0
⇒ y(2y + 9) - 3(2y + 9) = 0
⇒ (y - 3)(2y + 9) = 0
⇒ y = 3, -9/2{Neglect}
⇒ y = 3.
When y = 3:
⇒ x = y²
= 9
Therefore,total number of persons in the group is 9.
Characteristics:
(i) Punctual = √x = √9 = 3
(ii) Hardworking = 3
(iii) Disciplined = (x/3) = 9/3 = 3
Every character is better in their own way.
Hope it helps!
