The current depth of water in the river is 5 feet.
Using arithmetic operations we can find the water level of river.
Given that,
Usual depth of river = 8 feet
The increased water level after the rainfall = 3 feet
Therefore, the change in water level = 8 feet + 3 feet = 11 feet
The water level dropped next day = 6 feet
Then, the change in water level = 11 feet – 6 feet = 5 feet
That is the current depth of water in the river = 5 feet
