With both inlets open, a water tank will be filled with water in 48 minutes. The first inlet alone would fill the tank in 2 hours. What is the capacity of the tank, in cubic meters, if in every minute the second inlet admits 50 cubic meters of water more than the first?
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 \(\frac{1}{80}-\frac{1}{120}=50 \Rightarrow 1=12000 m^{3}\)]
