Coding-Decoding:
In a certain code language, `it pit sit` means `I am boy`, `it nit sit` means `I am girl`, which of the following means `girl`?
it
pit
sit
nit
Explanation:
We have,
`it pit sit` => I am boy.
`it nit sit` => I am girl.
Here, `it sit` is common in both the messages and `I am` is common in both codes.
Hence, code for girl will be `nit`.
