- work done by the leak in 1 hour=(1/6)-(2/13)=1/78
so leak can empty the tank in 78 hours........ - 13 years agoHelpfull: Yes(53) No(8)
- total time taken to fill due to leak=6+1/2=13/2
let it takes x hours to empty the tank
(1/6)-(1/x)=(2/13)
x=78/25 hours - 13 years agoHelpfull: Yes(6) No(17)

- Let the capacity of the tank be 6 liters then efficiency is 1 liter/hr.
If it took extra half an hour that means work done by leak in 6 hour and 30 minutes =work done by pipe in half hour.
So, it would be 12*6.5=78 hours - 9 years agoHelpfull: Yes(0) No(0)
- shortly
(6*6.5)/0.5 = 78 - 8 years agoHelpfull: Yes(0) No(0)
- Hey guys, I was wrong last time.
For 1 hour= 1/6+L=1/6.5.(1/1 Hour+30 mins=1.5 Hours)
=>L=1/6-1/6.5=1/78
So, In 78 Hours the whole tank get empty. - 6 years agoHelpfull: Yes(0) No(0)
