a.
To find: The time taken to empty the swimming pool in terms of
The function in terms of
Given:
The time taken by drainage
Calculation:
Let the volume of tank be
The rate at which drainage
The rate at which drainage
Combine both the rates to find the total rate at which both will empty the entire volume
Time taken to empty part
Conclusion:
The function in terms of
b.
To find: The time taken by drainage
The time take taken by drain
Given:

Calculation:
Graphical method:
Algebraic method:
The work done by drain A in
The work done by drain
The work done by both drains A and
So the equation will be as shown below.
Solve further to find the value of
Conclusion:
