Answer 1

choices

Answer 2

25%


33%


66%


75%

Answer 3

ok so what is 60 divided by 80

Answer 4

0.75

Answer 5

so wat is 75% - 100%

Answer 6

i hope you didnt put that as the answer

Answer 7

I would guess the percents are confusing.

Increase from 60 to 80.
Increase is 80 - 60 = 20
20 is what percent of 60?

Answer 8

r u sure

Answer 9

cause its not out of 80 its out of 100

Answer 10

I told you the percents were confusing.

20 is what % of 60?

Answer 11

30 percent but it is a test wich the highest you can score is a hundred so its based of that

Answer 12

30% is incorrect. 100 means nothing.

If I asked this, what would be the result?

I used to have 60 sheep.
Now I have 80 sheep.
What was the percent increase in my sheep population?

Answer 13

but are percents are out of a hundred so thats not the same case at all

Answer 14

It is exactly the same. This is why I said the percents might be confusing. 100 is still nothing.

We had 60%
We changed to 80%
What was the increase? 80% - 60% = 20%
What was the percent increase? 20% / 60% = 1/3 = 0.33333... = 33.3333%

We had 60 sheep
We changed to 80 sheep
What was the increase? 80 sheep - 60 sheep = 20 sheep
What was the percent increase? (20 sheep) / (60 sheep) = 1/3 = 0.33333... = 33.3333%

EXACTLY the same.

Answer 15

its 25% i have had this question and got it right

Answer 16

If that is so, and I have no reason to believe it is not as you have stated it, then the answer is incorrect. It is as I have stated it.

60 ==> 80 is a 33.333% increase.
80 ==> 60 is a 25% decrease.

It is a common point of confusion. You should challenge the author of the test and get this incorrect answer repaired. I suspect many other students have been misled by it.
