Question

By selling an article for Rs$400$ a man gains $25\%$. At what price should he sell the article to gain $20\%$?

Answer 1

CP of an object $=\frac{\left(100\right)}{(100+g)}\times$ SP

$=\frac{100}{125}\times 400$

$=$ Rs $320$

SP of the article for a gain of $20\%$

$=\left[\frac{(100+g)}{100}\right]\times$ CP

$=\left[\frac{(100+20)}{100}\right]\times 320$

$=\left[\frac{120}{100}\right]\times 320$

$=$ Rs $384$
