Answer with Step-by-step explanation:
The basic water balance dictates that "Amount of water flowing into the basin should be equal to the amount of water flowing out of it".
Mathematically

where
P = precipitation
I = Infiltration losses in the basin
E = Evapotranspiration
Q = is outflow from the basin
Applying the given values we get

Part b)
From the above equation we get

The evaporation in cubic meters per year is

Answer:
1: 3/4 = 6/8 = 9/12
2: 2/3 = 4/6 = 6/9
3: 8/9 = 16/18 = 24/27
Step-by-step explanation:
