SUMMARY
The problem involves a tank with a capacity of 90 liters containing a 20% chemical solution. To achieve a final strength of 30%, 15 liters of the 20% solution must be drained and replaced with an 80% solution. The calculation involves setting the total amount of chemical in the final solution equal to the desired concentration and solving for the volume of solution to be replaced.
