Answer 1

This is the answer...........

Answer 2

Answer:

i hope it will help

Step-by-step explanation:

Let the number of people in the group be x

One fourth of the group = (x/4)

Given that (2√x) of the group are caring

Number of people claiming optimistic = 15

Squaring on both the sides, we get

 

⇒ 9x2 – 360x – 64x + 3600 = 0

⇒ 9x2 – 424x + 3600 = 0

On solving the quadratic equation we get

x = 36 or x = (100/9)

But x cannot be fraction

Thus number of people in the group is 36.
