To find the answer, we can first find the age of Rolando in four year:

17+4
=21

We can then proceed to find the current age of Marisa,which is 3/2 of Rolando’s age calculated above:

Let Marisa’s age be y.

3/2 y =21
y = 21 × 2/3
y = 42/3
y = 14

Therefore Marisa is currently 14 years old.

In three years, Marisa would be:

14+3
=17

Therefore, she will be 17 years old.

Hope it helps!
