Question

jyothi does not eat bananas change it into passive voice

Answer 1

bananas are not eaten by Jyothi

Answer 2

The right answer will be: Bananas are not eaten by jyothi.

Here the subject is made object and the object is made subject but in no way the meaning of the sentence is changed.  

This is the rule of grammar that while changing a sentence in passive voice from active voice, tense, verb and the meaning will remain the same.
