If a tap could fill entire tank in 20 hrs due to leakage, then in how much time
tank can be emptied by leakage if tap can fill entire tank in 12 hrs without leakage
Choose the correct option
A) 30hrs  B) 24hrs  C) 36hrs  D) 48hrs  E) 52hrs
time take to fill[withleakage] =20hrs so workdone in 1hr=1/20   time tkae to fill[without leakage]=12hrs so workdone in 1hr=1/12   if u subtract both u'll get time taken by leakage to empty...   1/20-1/12=2/60 = 1/30 so 30hrs   30hrsNSWER:30hrs
