If something increases from 10% to 15%, do you consider that to be a 50% increase or a 5% increase?
If you said increased "by 50%" that would be correct. As in "it increase by 50% from 10 to 15%"
If you just say there was an increase, it would be 5%. As in "the was a 5% increase from 10 to 15%.
That's what I was thinking.
Which is 50% of 10...
Just because we are most likely comparing it to 100%, I said five. However, if you were saying that it rose fifty percent from the previous number then it makes sense.
There is no wrong answer. It depends on whether you view the increase from a multiplicative change (50% different) or an add/subtract change (5% different). I find the 50% interpretation to be more informative.
Clearly the education system in this country is still failing the fairer sex if only 28 out of every 100 females answered this question correctly. The only group with a worse ratio of correct answers are the youngsters.
Kinda depends on whether that is relative to the original number given, but since that is probably the case then it is obviously 5%.
Maine you have failed us again.
There's a definitive answer but it depends on your interpretation of the question.
*Little Hispanic Girl* Why can't we have both? -cheers-
Take a margin calculation for example: a 5% increase in margin from 10% to 15% equates to a greater than 50% increase in gross profit and markup even though the margin increase is exactly 5%. As a cashier for a Fortune 10 company, you should be able to understand that.
That's exactly the problem: you don't understand at all even though you claim to. It is both a 50% increase and a 5% increase at the same time; and it can also be many other numbers because the question is intentionally vague. If there was a clear answer would SOH have even asked it?
zod if I have 100% pennies and that 100% equates to 10 pennies. Add 5 pennies I have 5 more pennies over the initial 100% or the 10.....now I have 100% pennies still but the 100% has increase by 50%. If I have 10 pennies of 100 pennies ( 10 %) And Add 5 pennies the pennies increase 5 % (out of 100%
I am sorry I don't follow you zod and Ugandan .if I have 10 pennies I have 10 pennies......or 100% pennies. If I have 10% pennies I have 10 of 100 pennies. If I add 5 to my 10 pennies, my pennies increased by 50%. If I add 5% pennies to my 10% my pennies increased 10%. Again it's a matter of wheth
This is why the move to E15 gas is bad. You're increasing the ethanol content and it's destructive properties by 50%.
And I have been working for one of the fortune 10 companies for the last 15 years, which qualifies me to understand that going from 10% to 15% is a 50% increase not a 5% increase.
Yep, you are correct. The 5+ billion dollar credit portfolio I manage on a daily basis for one of the 25 largest companies on the planet clearly does not qualify me to answer a question like this. Thank you for your keen insight into my qualifications.
Ispots go back to school. You clearly dont understand the difference between "percent" and "percentage point". There is only one answer. How can you try to argue that an incorrect answer is correct?
He's saying that it would be correct to say, "the percentage increased by 5" (without the "%") because this statement means the numeric value of the percent is up by a quantity if five. He's also correct in saying that an overall percent increase is 50%
Which is exactly why he asked if you "consider" it a 5% increase, even though the actual "amount" does increase by 50%. (I said the same, btw. I just hope you read some of the comments in order to learn why you cant' simply add or subtract two numbers that way IF they're percents.)
Yes, I do "consider" that as a 5% increase, even though I "know" that mathematically it's actually a 50% increase. (5 is 50% of 10.) I'm glad he phrased this new math question this way -- that last one gave me SUCH a headache!
But really both sides have an argument based on the interpretation of he wuestion
The question asks if something increases from 10% to 15%, not if 10% increases to 15%. Therefore the answer is 5%. If 10% of 100is 10, 100 is the something, and 15% of 100 is 15, the increase from 10 to 15 is 5. 5/100 is 5%.
A math teacher would say 50%.
A P.E. teacher would say 5% :)
While my reading may have been incorrect Brian, his answer still doesn't make sense.
Your contribution raised by 5 percentage points. Which is a 50% increase over your previous contribution. You gave an additional 5%, but that wasn't what was asked. The question refers specifically to the increase. 50% is the only answer.
I am inclined to say 5% since the question refers 10% initially.
Thank you both for proving my point by not realizing that there are two correct answers and angrily suggesting that your perspective is the only one. My contribution has raised by 5% but the amount of my contribution has raised by 50%.
The question was 10% to 15%. So the rest of what you said is irrelevant.
Nope. Math is never about perspective. It's always absolute. 50% is the only possible answer.
Ha, what? It has nothing to do with perspective. Your contribution increase by 50%, not 5. If you want to use 5, then you would need to say that your contribution increased 5 percentage points.
What?? It had nothing to do with personality. In your scenario your contribution increased by 50%.
Maybe it's time to realize that not every question in the real world can be narrowed down to red or blue.
This question is all about perspective. If I have $100 and I tell you that you can have 10%, then you have $10. If I raise that to 15% then you now have $15. My contribution to you has raised by 5% but your collection has raised by 50%. The question says a lot more about personality type than math.
Interesting how the party of intellectuals has the highest percentage of the wrong answer...
last years sales were 100k. this years sales are 110k, a 10% increase. if sales move to 115k that is is actually a 4.5% increase from 110k
There is only one way to do math. It is a 50% increase.
theflash I agree - my wording to increase 1% by 1% is less clear than the original question or any of your examples. I could have said your tax rate was increased by an additional 1% of the taxable amount, making the new tax rate 2%.
Agree with flash. Not sure what language zod is speaking there?
Well then you would be wrong. It's a 50% increase or a 5 percentage point increase. Those are the only two answers. Given the question, the answer is 50.
that's how I feel too, but I could be wrong.
Nope, there is only one answer, 50%.
The only correct answer is 50%.
Your language here is a little bit confusing.
10% to 15% :
Increased by 50%
Increased by 5 percentage points
Increased by 500 basis points
Hope this clears things up.
UGAfan my pile of your pennies would be worth 55 cents, or 55% of a dollar. Using the form of the original question, my "something", a pile of pennies, increased from 50% to 55%, a 10% increase.
Your logic doesn't work. If you give me 50% of a dollar in pennies then another 5% of a dollar in pennies, how big's your pile?
What? Your first two examples are correct because get are numbers.
A percentage is NOT a number, it is a concept used to determine a number.
Honestly, it depends on how you look at it. If you think of both numbers as a percent of a whole, then it's 5. If you think of the actual amount each number represents, then it's 50.
Tony, you should ask if 0.99999999...= 1 next.
peaceNskis it's all in the spin. Your opponent may be just 5% less experienced, but you're also 50% more experienced - put together that's a 250% advantage. You can't lose!
