Question

a tank holds 200 litres of water due to a leakage the quantity reduces 5 litres every hour what will be its capacity after 10 hours.​

Answer 1

the pipe would have filled water in 200/5 = 40 hours if leak was not there.

the pipe took 80 hours more because of leak

=> the pipe worked for 40+80 hrs= 120 hrs and filled 120*5 litres = 600 litres

=> 600-200= 400 litres of water leaked out in 120 hours

Rate of leakage per hour = 400/120

= 3.33 ltr/hr
