• answer (3) both A and B
  
  A fill the tank in 8 hr
  But due to leak it take 12 hr
  
  now A fill the tank in 1 hr =1/8
  
  A fill the tank in 1 hr with leakage= 1/12
  
  so amount of leakage 1 hr= ( 1/8)- (1/12) = (4/96) =(1/24)
  
  Amount of leakage in 1 hr= (1/24)
  
  so total time it take to empty the tank is = 24
  
  ( i.e 24 hr = 1 full work done, empty the tank... complete work is always equal to 1)
