If a tap could fill entire tank in 15 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 choice:
A) 12hrs	B) 24hrs	C) 60hrs	D) 48hrs	E) 52hrs
time take to fill[withleakage] =15hrs so workdone in 1hr=1/15   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...   1/15-1/12=1/60 so 60hrs   ANSWER:60hrs
<result>C</result>
