members

Answer 1

The total number of green team members is 160.

Explanation:

Given:

There are 144 members at the meeting, which is 90% of the total group.

So, let the total number be
`x`.

According to question:

90% of
`x`=144.

⇒
`(90)/(100)* x=144`

⇒
`0.90* x=144`

⇒
`0.90x=144`

Now, dividing both sides by 0.90 we get:

⇒
`x=160`

Therefore, the total number of green team members is 160.
