A pipe is filling a tank of 200 litres capacity at 5 litres/hr.
Because of the leak it takes 80 hours more to fill the tank. What is the
rate in liters/hr at which the water is leaking?
Read Solution (Total 9)
-
- to fill the tank time required is 200/5=40
and 80hr more to fill due to leakage so 40+80=120
total rate=200/120=1.66
so leakage rate=5-1.66 nearly 3.33 - 12 years agoHelpfull: Yes(64) No(4)
- Time taken if no leak=200/5=40hrs
Actual time taken=80+40=120hrs
Let the rate at which water is leaking be xlitres/hr
So,
(5-x)*120=200
or,x=10/3=3.33 - 12 years agoHelpfull: Yes(12) No(2)
- 3.33 i think

- normally tank fills in 200/5 = 40 hrs
80 hrs more nneded. so it took 120 hrs (40+80)
rate of leaking be x say
rate of feeling = 5-x = 200/120 =5/3
x=5-5/3 = 10/3 = 3.33
ans : 3.33 ltr/hr - 12 years agoHelpfull: Yes(9) No(1)
- A fill 5 lit/hr=40 hr for 200liter
total:40hr+80hr= 120hr equals 1 2/3 lit/hr by A
B leakage 3 1/3 lit/hr
so ans is 3 1/3 lit/hr - 11 years agoHelpfull: Yes(3) No(1)
- 2.5 litre/hr

- without leak tank can b filld in 40hrs.
with leak it takes 120 hrs to fill d tank( i.e,40+80)
leakage in 1 hr=(1/40-1/120)=1/60
leak wl empty the tank in 200/60 hrs = 3.33lts/hr - 8 years agoHelpfull: Yes(1) No(0)
- yes..but how?
- 12 years agoHelpfull: Yes(0) No(9)
- its 2.5l/hr
- 12 years agoHelpfull: Yes(0) No(25)
