.If a pipe can fill the tank within 6 hrs but due to leak it took 30 min more
now if the tank was full hw much tym will it take to get emptyed through the leak??(i dont remembr whole sum exactly)(lil bit tricky sum)

• the amount of water that enters in 30 min(i.e 0.5hr), exits in 6.5 hrs.
  so, the amount of water that enters in 6 hrs, exits in (6.5/0.5)*6=78 hrs.
  
  ans:78hrs.

• time taken to fill tank is 6hrs
  thus amount of water pumpes is 1/6
  let rate of empyting t, thn amt of water emptied per hour s 1/t
  time taken to fill due to leak s 6.5 hr..
  per hour amt is 1/6.5
  thus we get
  1/6 - 1/t = 1/6.5
  thus t = 78 hours

• In one hour it will get emptyed through Leak = 1/6 - 2/13 = 1/78
  So it will take 78 hours to empty the tank through leak.

• workdone by the leak in 1 hour=(1/6-2/13)=1/78
  So 78 hours needed to empty the tank.
