15. Ankita bought 20 copy for Rs. 25 each. She got profit of Rs.200 while selling it. Find selling price of the copies. no​
goblinko [34]

Answer:

SP=Rs.700

Step-by-step explanation:

<em>cost</em><em> </em><em>price</em><em> </em><em>of a</em><em> </em><em>copy</em><em>=</em><em>R's</em><em>.</em><em>2</em><em>5</em>

<em>cost price of</em><em> </em><em>2</em><em>0</em><em>c</em><em>o</em><em>p</em><em>y</em><em>=</em><em>2</em><em>0</em><em>×</em><em>2</em><em>5</em><em>=</em><em>R</em><em>s</em><em>.</em><em>5</em><em>0</em><em>0</em>

<em>profit</em><em>=</em><em>Rs</em><em>.</em><em>2</em><em>0</em><em>0</em>

<em>selling</em><em> </em><em>price</em><em> </em><em>of</em><em> </em><em>2</em><em>0</em><em> </em><em>copies</em><em>=</em><em>?</em>

<em>Now</em><em>,</em><em> </em><em>we</em><em> </em><em>know</em><em> </em><em>that</em><em>,</em><em> </em>

<em>profit</em><em>=</em><em>sp-cp</em>

<em>or</em><em>,</em><em> </em><em>2</em><em>0</em><em>0</em><em>=</em><em>s</em><em>p</em><em>-</em><em>5</em><em>0</em><em>0</em>

<em>or</em><em>,</em><em> </em><em>2</em><em>0</em><em>0</em><em>+</em><em>5</em><em>0</em><em>0</em><em>=</em><em>s</em><em>p</em>

<em>thus</em><em>,</em><em> </em><em>SP</em><em>=</em><em>Rs</em><em>.</em><em>7</em><em>0</em><em>0</em>

Hence, the selling price of 20copies is 700.
