Why if you start out with number 100 increase it by 25 percent then decrease it by 20 percent and now your back to 100 again Why?
If you begin with 100 and increase it by 25%, predictably, you end up with 125. But when you decrease it by 20%, we're talking about 20% of the latest result, not of the original number. 20% of 125 is (125)*(0.2) = 25. So 125 - 25 brings you back to 100.
You cannot simplify or total the change in percent before calculating, because we're not always talking about the percent of the same number.

Does water volume increase when it is refrigerated?
If the water is above 4C in temperature ( above 40F) it will decrease in volume if refrigerated. When it reaches 40F then it will start to increase in volume, and when it freezes at 32F (0C) it increases a lot in volume when it becomes ice. After that, below 32C, it starts to decrease again.
How do you calculate a percentage change increase or decrease?
The simplest rule to never get confused: Always divide by the ORIGINAL value. Percent increase formula: (New - Old) / Old × 100 Percent decrease formula: (Old - New) / Old × 100 Notice the bottom number is always the starting value. Example: Price goes from 200 to 250 Difference = 50 50 / 200 = 0.25 0.25 × 100 = 25% increase Another example: 100 to 80 Difference = 20 20 / 100 = 0.20 So 20% decrease But going from 80 to 100 is NOT 20% increase 20 / 80 = 0.25 So it's actually 25% increase That’s where most people get confused — they divide by the wrong base. Quick mental trick: Find what fraction the difference is of the original. If 20 is one-fourth of 80, then it’s 25%. If you want to double check while practicing, you can use a calculator like this: mumbaipuneportal. com/percentage-increase-calculator But once you remember “difference divided by original”, you’ll rarely mess it up again.
What would happen to a food chain if there was an increase in the hawk population?
Hawk prey would decrease, and hawk predators would increase, making hawks decrease again. So to put it in context... Hawks eat mice, right? So the mouse population would increase, meaning more food for other animals that eat mice, like owls. So the owl population would increase, making mice decrease. Then animals that might eat hawks (I don't know if anything does) would increase, and eat all of the hawks then everything would eventually even out again.To answer your question, lots of things will happen, but it will all even out again.
Law of diminshing return?
The law of diminshing return is an term used in economics. It refers to how the marginal production of a factor of production starts to progressively decrease as the factor is increased, in contrast to the increase that would otherwise be normally expected. For example if you have a factory with a certain amount of floor space and employing a certain amount of employees, the output of the factory will increase if you increase the size of the floor space and/or the number of employees, perhaps on a one-for-on basis. However, at some point that relationship stops and eventually the rate of production increase begins to decrease (diminish) as you increase one of the variables. If, for example, you double the floor space and the number of employees, you might double (increase by 100%) the output of the factory. If you double them again, the output may only increase by 75% instead of 100%.
How do you calculate 5 percent of a number?
The easiest way is to divide by 10 then divide again by two.
What is the pattern in 7168279?
The number 7168279 appears to follow a pattern of alternating increasing and decreasing digits. Starting from the left, the digits increase from 1 to 8, then decrease from 8 to 2 before increasing again to 9. This creates a wave-like sequence where digits rise and fall. However, this pattern is not strictly consistent throughout the entire number.
What is the rate of increase in the price of scrap copper?
Scrap copper has dramatically seen a decrease in pricing along with other commodities. It is up over its historical lows, but again it is way off its historical high. So there has been no near term rate increase.
When the gold price will decrease again?

What number would complete the pattern below 107 98 90 83 77 68 65?
To identify the next number in the pattern, we can analyze the differences between consecutive numbers: 107 to 98 is a decrease of 9, 98 to 90 is a decrease of 8, 90 to 83 is a decrease of 7, 83 to 77 is a decrease of 6, and 77 to 68 is a decrease of 9. However, the last step from 68 to 65 is a decrease of 3. Continuing this pattern of decreasing numbers, the next decrease following the apparent trend (which seems to alternate between larger and smaller decreases) is likely 3 again. Thus, the next number in the sequence would be 65 - 3 = 62.
