Question

Price of an object increases by 25% and becomes $100. Find the original price.​

Answer 1

Answer:

Step-by-step explanation:

The percentage by which the new price must be decreased to obtain the original price is 25%.

Step-by-step explanation:

Let the price of the article = $100

It is given that, the price of the article is increased by 25%.

That is, the new price is increased by 25% of $100 = $25

Thus, the new price = $100 + $25 = $125

Now, it is required to decrease this new price in order to obtain the original price of $100.

As, we have that,

100 = 125 - 25

So, deceasing $125 by $25 gives us the original price.

Thus, the percentage by which the new price must be decreased to obtain the original price is 25%.
