From the looks of it, it looks like "8" would be your range. Just in case you don't know the definition of the word 'range' ... It is the 'mean' of all of your output values in the particular function.

<-----------|----|-------|------------->
7 9 15

Range: 7,15

Workout session: 15 - 7 = 8

9 would be ignored since it isn't the output part of the problem

Good Luck!

In a company, 80% of the workers are women. If 480 men work for the company, how many workers are there in all? Use pencil

Answer:

The total workers are 2400.

Step-by-step explanation:

Given:

In company 80% of the workers are women.

480 workers are men.

Now, to find the total workers in all.

In first way:

If women are 80%, then men would be 100-80 = 20%.

Let the total workers be $x$ .

According to question:

$20\%\ of \ x=480$

⇒ $\frac{20}{100} \times x=480$

⇒ $0.20\times x=480$

⇒ $0.20x=480$

Dividing both sides by 0.20 we get:

⇒ $x=2400$ .

Total workers = 2400.

Now, in second way.

Again, let the total workers be $x$ .

According to question:

$x-80\%\ of\ x=480$

⇒ $x-\frac{80}{100}\times x=480$

On solving:

⇒ $x-0.80x=480$

⇒ $0.20x=480$

Dividing both sides by 0.20 we get:

⇒ $x=2400$ .

Total workers = 2400.

Therefore, the total workers are 2400.
