A girl is carrying a bucket of water on her head from water reservoir situated near her house, the work done by her is?

 

There is no work done by the girl. She was carrying the bucket of water on her head. Meaning, the force is upward. The other force, which was when she was walking from the water reservoir to her house, is not parallel to the force applied to the bucket of water.

Remember: Force must be parallel to say that there is work done.
