Solution

Quantity of acid in the solution = 3 litres

Quantity of water in the solution = 7 litres

Let x litres of the acid be added in the solution.

∴ Total quantity of acid in the solution = (3 + x) litres

Total quantity of the solution = (7 + 3 + x) litres = (10 + x) litres

Percentage of acid in the solution =

The algebraic expression for percentage of acid in the solution is not a polynomial because the variable, x is in the denominator.
