If I had been hungry, I would have eaten something.

بھوک لگی ہوتی تو کچھ کھا لیتی۔

The past tense of the verb will that is given to us in the sentence is would

therefore the word would have been used to complete the sentence and the sentence is written as " if had been hungry, I would have eaten"
