Following bar graphs shows time taken by different pipes to fill that particular percentage of tank which is described in tabular data. For Ex- Pipe 1 fills the 10 % of tank in 6 mins.
Now, read the following data and answer the question carefully:


A Tank has three pipes; two of them are used to fil the tank while another one used to empty the tank namely: pipe 3, pipe 5 to fill the tank and a third pipe for making the tank empty. When all three pipes are open, 7/18th part of the tank is filled in 1 hours. How much time will the third pipe take to empty the completely filled tank 10 times the bigger than the previous one.
  • a)
    16.5 hrs
  • b)
    22.5 hrs
  • c)
    27 hrs
  • d)
    29.5 hrs
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
Following bar graphs shows time taken by different pipes to fill that ...
part of work in one hour=
(P3+P5+Third pipE. X 1 = 7/18th part of work
⇒ 7/18th part of work = 1 hr
⇒ Total work done = 18/7 hr by all three pipes
Pipe 3 does 50% of work in 90 mins
100 % of work = 90/50 * 100 = 180 mins = 3 hr
Pipe 5 does 50% of work in 60 mins
100 % of work = 60/50 * 100 = 120 mins = 2 hr
Time Tw Efficiency
Pipe -3 = 3 hr Total work/3 = 6
Pipe-5 = 2 hr Total work/2 = 9
All three = 18/7 hr Total work/(18/7)= 7
For Total work = LCM of (3,2,18/7) = 18
Efficiency of pipe 3 + Efficiency of pipe 5 + Efficiency of third pipe = total efficiency
6+9+X= 7
X = 7-15 = -8 (Negative sign shows the negative work herE.
Efficiency X Time = Total work
8 X Time = 18 * 10 ( as tank is 10 times bigger than the previous onE.
Time = 180/8 = 22.5 hrs
