</li></ol> <h2 id="content-id-2809357614-5"><b> Time And Work Questions Solution</b></h2><p>The correct answer is <strong>option 4 </strong>i.e.<strong> 40 days.</strong></p>

<p>Let 1 boy’s 1 day work = b, 1 girl’s = g</p>

<p>4b + 6g = 1/8</p>

<p>⇒ 12b + 18g = 3/8 …(1)</p>

<p>3b + 7g = 1/10</p>

<p>⇒ 12b + 28g = 4/10 = 2/5 …(2)</p>

<p>(2) - (1): (12b+28g) – (12b+18g) = 2/5 – 3/8</p>

<p>⇒ 10g = 16/40 – 15/40 = 1/40</p>

<p>⇒ g = 1/400</p>

<p>10 girls 1 day work = 10/400 = 1/40</p>

<p>⇒ Time = 40 days</p>
