Answer:
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
