We are given that, the amt. of water decreases at a constant rate.
This means that,
To get its General Solution (GS), integrating term-wise,
To determine the consts.
Solving
Then,
desired relation!
Capacity of the tank L = 5400 litres , rate of decrease of water - x = 120 litres per day
Explanation:
Given : L - total volume of the tank
After 20 days
After (20 + 15) days,
Subtracting Eqn (2) from (10,
Substituting value of x in Equation (1),
L = 3000 + 2400 = 5400 litres#
