Question

15% increase in price of an article, which is Rs 1620, is the increase of Rs ___

Answer 1

Let the price of the article be Rs x.
After $15\%$ increased in price, price became Rs. $1620$,
So, $1620=x+x\times \frac{15}{100}$
$\Rightarrow 1620=\frac{115x}{100}$
$\Rightarrow 115x=1620\times 100$
$\Rightarrow x=\frac{1620\times 100}{115}$
$\Rightarrow x=Rs1408.7$
Hence, increase in price = Rs 1620 - Rs 1408 = Rs 211.3
