</li></ol> <h2 id="content-id-6312578904-5"><b> Pipes And Cistern Questions Solution</b></h2><p>The correct answer is<strong> option 4</strong> i.e. <strong>70 hours.</strong></p>

<p>Combined rate of A and B = 1/20 + 1/30 = 1/12</p>

<p>Time for A + B to fill the tank = 12 hours</p>

<p>Time for all three pipes = 12 + 4/3 = 40/3 hours</p>

<p>Combined rate (A + B - C) = 3/40</p>

<p>1/12 - 1/C = 3/40</p>

<p>⇒ 1/C = 1/12 - 3/40 = 1/120</p>

<p>Amount filled in 7 hours by (A + B) = 7 × (1/12) = 7/12</p>

<p>Time for C to empty = (7/12)/(1/120) = 70 hours</p>
