</li></ol> <h2 id="content-id-3716508924-5"><b> Data Sufficiency Questions Solution</b></h2><p>The correct answer is <strong>option 3 </strong>i.e <strong>Rs.120</strong></p>

<p>Let the cost price of the first book in the transaction be Rs.y, then the cost price of the second book becomes Rs. (300 - y).</p>

<p>He sells the first book at 20% profit, then the selling price = 1.2y</p>

<p>He sells the second book at a 10% loss, then the selling price = 0.9(300 - y)</p>

<p>⇒ 270 - 0.9y</p>

<p>Total selling price ⇒ 1.2y + 270 - 0.9y = 300</p>

<p>⇒ 0.3y + 270 = 300</p>

<p>⇒ 0.3y = 30</p>

<p>⇒ y = Rs.100</p>

<p>Selling price of the first book = 1.2y = 1.2(100)</p>

<p>⇒ Rs.120</p>
