</li></ol> <h2 id="content-id-7058642931-5"><b> HCF And LCM Questions Solution</b></h2><p>The correct answer is <strong>Option 1</strong> i.e. <strong>12.</strong></p>

<p>Let present ages be: P = x, Q = y</p>

<p>8x − y = 12 ...(1)</p>

<p>After 8 years:</p>

<p>3(y + 8) = 8(x + 8) − 28</p>

<p>3y + 24 = 8x + 36</p>

<p>3y = 8x + 12 ...(2)</p>

<p>From (1): y = 8x − 12</p>

<p>Put in (2):</p>

<p>3(8x − 12) = 8x + 12</p>

<p>24x − 36 = 8x + 12</p>

<p>16x = 48</p>

<p>x = 3</p>

<p>y = 8(3) − 12 = 12</p>

<p>Present age of Q = 12 years</p>
