An outlet pipe can empty a cistern in 30 min, then what part of the cistern will it empty in 1 min?

1/20
1/15
1/30
1/18

Correct Answer: 1/30

Explanation:

We know that, when a pipe empties a cistern in n min, then the part emptied by the pipe in 1 min = 1/n
Here, n=30
∴ Required part of the tank emptied in 1 min = 1/30 part
