The answer is 25 %

Step-by-step explanation:

Because if the price of a box of pencil = rs100 if he decrease 25% it cost will be rs 75 then again to make rs100 he have to increase 25%

Answer 2

There is $33\dfrac{1}{3}\%$ increment in the product back to its original price.

Step-by-step explanation:

Since we have given that

If the price of one product  is reduced by 25%

then, we need to find the percentage of the reduced price must it be increased by to put the product back to its original price,

So, it becomes,

$\dfrac{r}{100-r}\times 100\\\\=\dfrac{25}{100-25}\times 100\\\\=\dfrac{25}{75}\times 100\\\\=\dfrac{1}{3}\times 100\\\\=33\dfrac{1}{3}\%$

Hence, there is $33\dfrac{1}{3}\%$ increment in the product back to its original price.
