After lunch, she has eaten .
Hence all in all she has eaten of her orange.
Well, think about it:
Before lunch she ate 5/12 of the orange, which leaves 7/12 of the orange BEFORE lunch.
AFTER lunch, she ate 5/12 of the remaining 7/12, and that is . That is the portion eaten AFTER lunch. So the portion eaten BEFORE lunch, PLUS the portion eaten AFTER lunch must be of the orange.
