Only 2.5% of Hydrosphere are freshwater, if only 31% of it are groundwater which we can drink right away, how many percent of our hydrosphere can be used as drinking water? a. 0.78%
b. 1.73%
c. 12.4%
d. 28.5%

a. 0.78%

Explanation:

Given data:

Total percentage of hydrosphere = 2.5%

Percentage of ground water = 31%

Percentage of hydrosphere we use for drinking = ?

Solution:

Percentage of hydrosphere we use for drinking  = Percentage of ground water /100 × Total percentage of hydrosphere

By putting values,

Percentage of hydrosphere we use for drinking = 31 / 100× 2.5

Percentage of hydrosphere we use for drinking = 0.78%
