Two tanks A and B.A fills 1ltr/1hr B fills 10,20,30 per hour.If 1/4th of tank B takes 15 hrs to fill how much it time will to take to fill complete tank?

• I think..18 hrs is the answer
  B fills 10,2*10,3*10 per hr
  so for
  1/4 ---->15 hrs
  2(1/4)-->16 hrs
  3(1/4)-->17 hrs
  4(1/4)ie..tank is filled now takes->18 hrs

• answer:18 hours
  suppose the tank b capacity is 100 litres
  (1/4)*100=15 hours
  =25 litres filled in 15 hours
  50 litres filled in 16 hours
  75 litres fill in 17 hours
  100 litres fill in 18 hours

• B fills 1/4 in 15hrs... When compared to A it fills twice.
  So. 1/4= 15 hrs
  2(1/4)=16 hrs
  2(1/2)=17 hrs....
  hence to complete the tank it takes 17 hrs...
