Answer:
Filling takes 5hrs=300mt
In one minute filling rate
=V/300
Emptying time 8hrs
One minute emptying rate
=V/480
If both the taps are open
Simultaneously the tank water filling rate/minute
=V/300-V/480
=V(8–5)/2400
=V3/2400
=V/800
The tank should get filled up in 800 MTs or800/60
=13hrs and 20mts
