<p>Ratio of boys : girls = 7 : 5</p>

<p>Total trainees = 120</p>

<p>Boys = (7/12) × 120</p>

<p>= 70</p>

<p>Girls = (5/12) × 120</p>

<p>= 50</p>

<p>Using weighted average,</p>

<p>120x = 70(x − 10) + 50 × 164</p>

<p>120x = 70x − 700 + 8200</p>

<p>50x = 7500</p>

<p>x = 150</p>

<p>Required value</p>

<p>= (x / 5) + 20</p>
