hi frens im from india and wud lik to study in warsaw, poland. Is it possiible for me to do my master's degree along with part time jobs workin for 15-20 hours a week.
15-20 hours shouldn't be a big obstacle in your studies, however I don't think it is easy (or possible) to obtain study and work visa.
The best option for you is to contact Polish Consulate in India. They will give you the most accurate informations about visa, working and studying in Poland.
