Question

if one pipe a can fill a tank in 20 minutes then 5 pipes each of 20% efficiency of a can fill the tank in​

Answer 1

Answer:

20 minutes

Step-by-step explanation:

Efficiency of pipe A,

10020

= 5%

20% of efficiency of A = 1%

Then, efficiency of 5 such pipes = 5%.

Then,

Time taken to fill the tank = 100 / 5

= 20 min.
