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:
A. 80 min
B. 100 min
C. 20 min
D. 25 min
Answer: Option C
Solution (By Examveda Team)
Efficiency of pipe A, $$\frac{{100}}{{20}}$$ = 5% 20% of efficiency of A = 1% Then, efficiency of 5 such pipes = 5%. Then,Time taken to fill the tank = $$\frac{{100}}{5}$$ = 20 min.This Question Belongs to Arithmetic Ability >> Time And Work
Efficiency ratio , A: each pipe of other=100:20=5:1
So, their time ratio= 1:5
So, If A take 20 minutes to fill the tank, then each of other pipe take =5*20= 100 minutes.
Let, capacity of the tank be 100 units.
A 's 1 minutes's w
