<p>Females = 40000 ⇒ Males = 70000 − 40000 = 30000</p>

<p>Females after increase = 40000 × 104/100 = 41600</p>

<p>Males after increase = 30000 × (100 + x)/100</p>

<p>Total after increase = 73600</p>

<p>30000 × (100 + x)/100 + 41600 = 73600</p>

<p>300(100 + x) + 41600 = 73600</p>

<p>30000 + 300x = 32000</p>

<p>300x = 2000</p>

<p>3x = 20</p>
