The correct option is A 500
Percolation rate is the amount of water that trickles into the soil in a given time. It is calculated as follows:
Percolation rate = Amount of water percolated(ml)Time taken(minutes)
Given,
Amount of water taken: x ml
Time taken by water to percolate: 50 min
Percolation rate= 10 ml/min)
Percolation rate=
Amount of water takenTime taken by water to percolate=x ml50 min=10 ml/min
Therefore, the amount of water percolalted (x) = 500 ml
