Melody:
I'm looking at your answer and I'm not sure if it's right.
You said that...
Ana is oldest, then Beatriz, and the youngest is Celia
This contradicts all three statements that buubleman provided.
In your statement,
Beatriz is NOT oldest...
Ana IS oldest...
and Celia IS the youngest.
However, if I'm correct, Statement 3: Celia is not the youngest, is true, then that would mean Ana not being oldest would be false and Beatriz being oldest has to be false.
To do that, you could have Ana being oldest, Celia in the middle, and Beatriz youngest.
Is Ana oldest, Celia next, and Beatriz youngest correct, Buubleman?
