Hi anil,
this is going to be a little tougher than i believe. as you will get a furnish house in quatre bornes around 6000 MUR , and the food around 3000 MUR, the party + transport around 5000.
Your appartment will be furnished. Ask the dcdm people to find a place for you within this budget. you will be able to save >10000 if you can manage . Well i am sure you will anil.
Tax is 13 to 15 % of your pay.
Just Keep your hands tight and wait till you are here to experience mauritius .
