Answer: Her salary must increase by 25% after the trial period to match her old salary.

Step-by-step explanation:

Since we have given that

Windy has 20% less salary than she had on her old job.

Let the salary of her old job be 100

So, the salary of new job for the trial period be

\frac{100-20}{100}\times 100\\\\=\frac{80}{100}\times 100\\\\=Rs.80

We need to find the percentage of her salary should increase after the trial period to match her old salary.

So, her new salary for the trial period becomes the base salary or original salary, as it is said that it must increase from trial period to match old salary.

So, she need to increase Rs. 80 to Rs. 100 again.

\frac{Difference}{Original}\times 100\\\\=\frac{100-80}{80}\times 100\\\\=\frac{20}{80}\times 100\\\\=25\%

Hence, her salary must increase by 25% after the trial period to match her old salary.
