</li></ol> <h2 id="content-id-5807462913-4"><b>Solution</b></h2><p>The correct answer is <strong>option 5</strong> i.e.<strong> 15 min.</strong></p>

<p>A can fill the tank = 10 min</p>

<p>B can fill the tank = 15 min</p>

<p>Let's assume C can empty the tank = x min</p>

<p>So, the capacity of the tank = 30x</p>

<p>Efficiency of A, B, and C = 3x, 2x, and -30.</p>

<p>If only Pipe A and B are open then total time = 30x/(3x + 2x) = 6 min</p>

<p>Due to pipe C, total time = 6 + 4 = 10 min</p>

<p>30x/(3x + 2x - 30) = 10</p>

<p>3x = 5x - 30</p>

<p>x = 15</p>

<p>So, Pipe C can empty the tank = 15 min</p>

</li></ol> <h2 id="content-id-0182376954-5"><b>Solution</b></h2><p>The correct answer is <strong>Option 2 </strong>i.e. <strong>170.</strong></p>

<p>Total capacity of tank = LCM of 16 and 12 = 48 units</p>

<p>Efficiency of Pipe A = 48/16 = 3 units</p>

<p>Efficiency of Pipe B = 48/12 = 4 units</p>

<p>Amount of tank filled by them in 2 hours = 7 × 2 = 14 units</p>

<p>Hence, tank left = (48 - 14) = 34 units</p>

<p>But according to question = 48 units = 240 litres</p>
