Question

The price of an article has been reduced by 35%. In order to restore the original price,by how much the new price must be increased ?

Answer 1

New price = x= 0.75 of odd price

Let old price = y $\Rightarrow x=0.75y$

$\Rightarrow x=\frac{75}{100}y\Rightarrow x=\frac{3}{4}y$

$\Rightarrow y=\frac{4}{3}x=1.333x$

So the price must be increased by 33.33% which is about 33.3%
