food (groceries)-- dis wont cost u much campared to ur sal.

cell phone-- its 200 QR for the sim card if prepaid and the call charges are ok

car payments (120 QAD total loan)-- taking the 120,000 is for both the cars means ur payment approx for each month for both the cars wil be lik 3600 QR but u better chk out some bank site the loan calc is available online.

eating out-- depending on which country food and type of resta

clothes-- it also depends on wht brands u want to buy.

but i guess 22k u should be more thn ok.
