100% + 25% = 100% . How exactly did that happen?

Question

Math wizards is this equation seriously right?


thanks in advance for your answer/s! ^.^

Answer 1

in theory, you can't go above 100%. It all depends what you are talking about. As an equation its wrong. its 125%, but since you can't go above 100%, then its 100%.

If you are figuring out, for example, the price increase in something you can go above 100%

Answer 2

This is an interesting one. It is more related to the definition of terms and what you mean than to math.

If you plan to raise $100,000 and you actually raise $125,000 or if your airplane engine has 100 hp and you replace it with a 225 hp engine you have 2 cases where the actual increase is 125% and 100 % + 25 % = 125 % and this is the accurate answer.

Now lets talk probability. Let's assume there is a 100 % probability of rain tomorrow due to a front coming in from the north west as of the 8:00 a.m. forecast. This means it will rain (100 % probability). At 6:00 p.m. the forecast also indicates a second front with a 25 % rain chance is probable for tomorrow too. It is already going to rain, 100% probabality, from the first front for tomorrow. The second front has a 25 % probability of rain for tomorrow. You cannot have more than a 100 % probability for rain so in this case 100 % + 25 % = 100 %.

Again, go back to the definition of terms and how they are used.

At this time you probably feel the problem is not a math problem but a philosophy one - and that is a decent conclusion. Consider 2 lawyers in a court room pushing their respective viewpoint - this is exactly what they do; if they cannot prove something based on logic they look for definition or circumstance or philosophy.

And you thought math was clear cut - sorry that is not always the case

Answer 3

GTB said it very well. To say it more simply, it all depends on *what you are asking*. If you need 2 dollar and get $2.50 dollars you have 125% of your target, or 25% than your initial amount. If you give that $2.50 to someone you have given that person 100% of your money. You have none left so you can't give them "125%" of your money.

When the maximum is fixed this is 100%. The most you can give of yourself in a sport is %100; nothing more. If you can give more than you weren't giving 100% in the first place.

Answer 4

GTB and Mentat are perfectly correct.

Remember that a percentage is not an object - it is a FRACTION of something. Numbers have no meaning alone, they are an abstract representation of a state, whether probability or money, and what can be correct for one situation may be ridiculous for another.

In the same way, 1 + 1 = 1 can famously be proven correct. A probability of 1 means something will happen, and when increased by 1 it still has a 100% chance of happening.

Answer 5

100% + 25% = 125%
Does that look better to you?

Of course it is possible to have more than 100%!!!
For example, you raised 100% of the funds and then you got 25% more funds. Well, you have just raised 125% of the money that you needed. You can save the extra for the next fundraiser.

Answer 6

ok i will use an example to try and explain this.

If you have $100 then thats 100% of your money.

Then if you add another 25% ($25) you will have a new total of $125.

Now 100% of your money is $125.

Therefore you still have a 100% but the value of 100% has changed.


Hope this helps

Answer 7

You must also ask percent of what (which depends on the problem at hand). For example I could take 100% of sample A and mix it with 25% of sample B to get 100% of the mixture C.

Answer 8

Mathematically, it isn't right; it is 125%. However, if talking about individual productivity, 100% is the limit. Forget what coaches and bosses tell you about "giving 110%" because it isn't possible. If you exert yourself, you are giving all you have, and that is 100%, which is a whole. 125% is more than whole, and no human alive has more than what they have, from an endurance and productivity point of view.

Answer 9

The total of anything is 100%... so if you have 20 pencils, then 20 is 100% of the pencils you own. If you get 5 more pencils, then 25 becomes 100% of the pencils you own.
100%(20) + 25%(5) = (new)100%(25).

Answer 10

No, it's not. 100% added to 25% is obviously equals to 125%. Is there any logic behind it? However, if you're going to limit it to the ideal maximum percentage, then it would come up by 100%.
