Profit or loss question..please solve this​
Yuki888 [10]

<em>Answer:</em>

<em>I would say he makes 10.5%</em>

<em>Step-by-step explanation:</em>

<em />

<em>Let the price at which the shopkeeper bought the article be 100. </em>

<em>Since he has to make a profit of 30%, he would mark the price as 130. </em>

<em>Now, he allows a discount of 15% i.e. 15% of 130 = 19.5 </em>

<em>The actual discounted price= 130–19.5= 110.5 </em>

<em> </em>

<u><em>He gets 10.5 on 100. The profit percent he makes is 10.5%</em></u>
