In the question, we are asked for the quantity of water that must be evaporated from 24 ounces of a 5% salt solution to make a 6% salt solution.

The initial quantity of the solution is given to be 24 ounces.

The amount of salt in it is 5%, that is, 5% of 24 ounces = 1.2 ounces.

We assume the quantity of water evaporated from the solution to be x ounces.

Thus, the final quantity of the solution is 24 - x ounces.

But, the amount of salt remains constant at 1.2 ounces.

Now, we are asked for evaporation, such that the solution contains 6% salt.

This can be shown as:

1.2/(24 - x) = 6%.

To get the value of x, we solve this as:

1.2/(24 - x) = 6%,

or, 24 - x = 1.2/6%,

or, 24 - x = 20,

or, x = 24 - 20,

or, x = 4.

Thus, to obtain a solution that is 6% salt, 4 ounces of water must be evaporated.
