</li><li><p>40 years</p>
</li></ol> <h2 id="content-id-4931726085-5"><b> Average Questions Solution</b></h2><p>The correct answer is <strong>Option 5 </strong>i.e. <strong>40 years.</strong></p>

<p>Sum of all the items in the group = (Average of the group) × (Number of items in the group)</p>

<p>Let the age of the eldest and youngest member in the group be 'E' and 'Y'</p>

<p>Given E - Y = 4</p>

<p>Sum of the remaining 3 persons in the group (excluding eldest and youngest) = 3 × 28 = 84 </p>

<p>Sum of ages of all the members in the group = 5 × 32 = 160</p>

<p>E + Y + (Sum of all the remaining) = 160</p>

<p>E + Y = 160 - 84 = 76</p>

<p>Solving</p>

<p>E - Y = 4</p>

<p>E + Y = 76</p>

<p>We get E = 40 years</p>

<p>Y = 36 years</p>
