By Selling 5 articles for 18rupee, a man losses 10%. If he sells 3 articles for Rs. 15, then what will be the profit percentage?1). 752). 66.673). 304). 25

Answer»

LET, cost price of 5 article = Rs. x

Price at 10% loss = Rs. 18

According to PROBLEM,

⇒ x - x × 10/100 = 18

⇒ 0.9x = 18

⇒ x = 20

∴ Cost price of 5 article = Rs. 20

∴ Cost price of 3 article = Rs. 20 × 3/5 = Rs. 12

Selling price of 3 article = Rs. 15

∴ Profit percentage,

$( \Rightarrow \frac{{15 - 12}}{{12}} \TIMES 100\% )$ 

⇒ 25%
