</li></ol> <h2 id="content-id-8349126507-6"><b> Number System Questions Solution</b></h2><p>The correct answer is <strong>option 1</strong> i.e. <strong>5.</strong></p>

<p>Let the odd numbers be:</p>

<p>x, x + 2, x + 4</p>

<p>Largest odd number = x + 4</p>

<p>Smallest even number = x + 11</p>

<p>So even numbers are:</p>

<p>x + 11, x + 13, x + 15</p>

<p>Average of odd numbers = x + 2</p>

<p>Average of even numbers = x + 13</p>

<p>According to question:</p>

<p>(x + 13)<sup>2</sup> − (x + 2)<sup>2</sup> = 275</p>

<p>⇒ [(x + 13) − (x + 2)] × [(x + 13) + (x + 2)] = 275</p>

<p>⇒ 11 × (2x + 15) = 275</p>

<p>⇒ 2x + 15 = 25</p>

<p>⇒ x = 5</p>

<p>Smallest odd number = 5</p>
