Oh Rajahmundry...... Hmmmm... Ive never really been around the place but Ive passed through it many times....
Its not really a big city in India.... not many people would not know of it... Its in the state of Andhra Pradesh. Hyderabad is a famous city in Andhra Pradesh(or A.P. as its called) .
The people here primarily speak "Telgu". I would not rank it as an easy to learn language. However, as is the case is nost southern states, English is spoken fairly widely. Id expect a majority of the people to speak atleast a little bit of english.
Sorry if this is disappointing.
Rajahmundry has mostly Chemical industries. Its not high on the tourism barometer either. Some temples to visit around but thats it.
Im sure you can get some more info. on this place if you google it.
Also , it is a very hot place.
