Answer / mohit

suppose the capacity of cistern is 30unit. when it id repaired
then takes 3 hrs.thus water coming in i hrs=10unit.
now leak tank takes 3 hrs and 1/2 hrs extra. that is, in
general think that the water filling in 1/2 hrs is equal to
the leakage of hole in 3.5 hrs.
leakage in 3.5 hrs is =10/2=5 unit
so 5 unit is leakad in =3.5 hrs
so 30unit(full capacity) is leaked in =3.5*30/5
=21 hrs
so it will take 21 hrs to empty the full cistern.

Answer / godwin justin

Let's assume the tank has 12 litres capacity. The pipe can fill in 3 hours therefore efficiency= 12/3=4. Now the leak caused the tank to be filled in 3 1/2 hrs.
Total capacity/efficiency of pipe-efficiency of leak=time taken
ie,12/4-x=7/2
X=(28-24)/7= 4/7 which is the efficiency of d leak.
So time take by the leak to empty the tank is:
12÷ 4/7 12*7/4= 7*3 = 21 hours

Answer / sagarkumar doltade

LCM of repaired tank and leak tank time=3*3.5=10.5 difference between efficiency is 1/2 then 10.5/1/2=21

Answer / vidhya

usual time 4(half an hour longer) -->x
ue to leak 3.5-->y
formula =x*y/x-y=>4*3.5/0.5=28 hours

Answer / pradeep

the amount of work done by the leak in one hour is
(2/7)-(1/4)=1/28....
Therefore the amount required to empty the whole tank is 28
hours
