There is a solution of salt in a flask. From the flask, \( \frac{1}{n} \) part of the solution is poured into a test tube, and the remaining solution in the flask is evaporated until the percentage of salt content doubles. After that, the solution from the test tube is poured back into the flask. As a result, the salt content in the solution increased by \( p \% \) compared to the original. Determine the initial percentage concentration of the salt in the solution. What part of the original solution should have been poured to increase the salt content by one and a half times as a result of the described procedure?
