Answer 2

Given:

A store raised the price of an item by exactly 10 percent.

To Find:

Resulting price of the item?

Step-by-step explanation:

Let the original price of an item be X Rs and it is increased by 10 percent then let the total amount be  YRs.

According to the given condition in question:

110% of the Original price is equal to the increased amount

110% of X =Y

We know that  110 percent of X is:   $\frac{110}{100} \times X$ and it is equal to Y, which can be written as,

$\frac{110}{100} \times X =Y$

Original price of the item is :

$X= \frac{100}{110}\times Y$

$X=\frac{10}{11}\times Y$

Hence, Original price = $\frac{10}{11}\times$ Increased price

Put the options in place of increased price, We will get the answer.
