Rosa is 10. -- further-- This is calculated by working out the relationship between the children. Let's call Rosa "R" and let that stand for her age.

The next child is R + 2 years old and the eldest if R + 4. We are told that R + (R + 2) + (R + 4) = 36 (add the Rs and the digits on the left)

R + R + R + 2 + 4 = 36

3R + 6 = 36 (subtract 6 from both sides)

3R = 36 - 6 3R = 30 (divide both sides by 3) R = 10According to the information given, Rosa is ten years old.
