Question

The cost price of an article is 30 percent less than its selling price. Find, the profit or the loss as percent.

Answer 1

Let S.P. of the article = Rs.100
30% of S.P. =Rs.$\frac{30}{100}\times 100$ = Rs. 30
$\therefore$ C.P. of the article = 100-30 = Rs. 70
Profit = S.P.-C.P.
= Rs. 100- Rs.70 = Rs. 30
Profit% = $\frac{Profit}{C.P.}\times 100$
= $\frac{30}{70}\times 100=\frac{300}{7}$%
