A tank is filled in 10 hours by three pipes A, B and C.
A tank is filled in 10 hours by three pipes A, B and C. Pipe C is twice as fast as B and B is twice as fast as A. How much time will pipe A alone take to fill the tank?
Answer/Solution
70 hours
Steps/Work
Efficiency of pipes A,B,C =1:2:4
Therefore, in 10 hours, part of the tank filled by A =17
Therefore, pipe A alone requires 10×7=70 hours to fill the tank.
Answer: Option A
Therefore, in 10 hours, part of the tank filled by A =17
Therefore, pipe A alone requires 10×7=70 hours to fill the tank.
Answer: Option A
