Satish, I think if you do a search you'll find lots of answers to your questions. It totally depends on your spending habits, where you want to live and what you want to drive. For example, a 2 bedroom flat will cost you anything from QR7500 up to QR16500. If you decide to rent a car you'll pay around QR1800 for a small salon. Foodwise you'll pay around QR1000 per week (or more if you like to indulge).
