Explanation: দুটি inlet একসাথে কাজ করলে, 48 min এ ভরে \(\frac{1}{48}\) অংশ \(\therefore 1^{st}\) inlet 1 min এ ভরে \(\frac{1}{120}\) অংশ অতএব, \(2^{nd}\) inlet 1 min এ ভরে \(\left(\frac{1}{48}-\frac{1}{120}\right) = \frac{1}{80}\) অংশ অর্থাৎ \(\frac{1}{80}-\frac{1}{120}=50 \Rightarrow 1=12000 m^{3}\)]
