Answer:

Age of Alice=25 years

Age of Jane=20 years

Step-by-step explanation:

We are given that the age of Jane is 80 % of the age Alice.

We have to find the age of Jane and Alice.

Let x be the age of Alice

According to question

Age of Jane=80% of Alice=80% of x=\frac{80}{100}\times x=\frac{4x}{5}

x+\frac{4x}{5}=45

\frac{5x+4x}{5}=45

\frac{9x}{5}=45

x=\frac{45\times 5}{9}=25

Age of Alice=25 years

Age of Jane=\frac{4}{5}\times 25=20 years

Age of Jane=20 years
