Answer» Given :- If an inlet pipe can fill a tank in 4 hours and an outlet pipe can empty the full tank in 5 hours, then what is the portion of the tank filled in 1 HOUR if both the PIPES are kept open ? Solution :- → In 4 hours inlet pipe fill = 1 tank so, → In 1 hour inlet pipe will fill = (1/4) of tank . similarly, → In 5 hours outlet pipe empty = 1 tank so, → In 1 hour outlet pipe will empty = (1/5) of tank . then, → Both will fill in 1 hour = (1/4) - (1/5) = (5 - 4) /20 = (1/20) portion of the tank .
