two tanks A and B, A fills 1litre/1 hour. B fills 10,20,30. per hour two tanks A and B, A fills 1litre/1 hour. B fills 10,20,30. per hour. if 1/4th tank of B takes 15 hour to fill. how much time it will take to fill complete the tank

• its 17th hrs...as 1/2^2 so 15+2=17

• 1/4th of the tank takes:15 hours
  so full tank(i.e 1)takes:?
  t=15/(1/4)=15*4=60 hours

• in tank b, 1 hr=10 ltr. so, 15 hr = 150 ltr .
  1/4 of the tank = 150 ltr
  1 tank = 600 ltr
  so,
  600 ltr = 60 hr . in tank b it fill the tank in 60 hour

• B fills as 10,20,30.... so it increases as +10 liters every hour.
  therefore assume B=x+10 for every hour,
  at 15th hour it is (x+10)/4 (given in the question)
  at 16th hour it is 2(x+10)/4 ==> (x+10)/2 ==> half of the tank is filled
  at 17th hour it is 3(x+10)/4 ==> 3/4th of the tank is filled
  at 18th hour it is 4(x+10)/4 ==> x+10 ==> therefore at the 18th hour the tank is completly filled.
  or the question may also be solved as
  for 15th hour it is x/4,
  for 16th hour it is 2x/4 ==> x/2
  for 17th hour 3x/4
  and for 18th hour it is 4x/4 ==> x, hence the tank is filled

• the rates are given as 10,20,30 ie linearly not like 10,20,40,80,160.....there are pretty much difference between those two questions.it will be simple 1/4 takes 15 hr.then 1 part will take 15*4=60 hours

• B fills 10lt/hr so in 15 hrs it'll fill 150 lt...
  if 150lt is 1/4th then full tank =150*4=600lt
  hence to fill 600lt ie, full tank= 600/10= 60hrs

• 1/4th first we have to find 4=2^2 so t6he power of 2 is 2 now add it with 15hour
  so 15+2=17 hour :)

• 17hours..
  as x/4 in 15 hrs den
  2*(x/4) in 16hrs and
  2*(x/2) in 17hrs

• At 16th hour- 1/2 of the tank fills
  17 """ 1 i.e.full
• 13 years agoHelpfull: Yes(0) No(1)
• 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 (given in statement)
  75 litres fill in 17 hours (given)
  100 litres fill in 18 hours (given)
