LOL.XD.. QAR500 per month for food?? What are you eating? I am on strict diet and I spend about 200QAR per week for my grocery.. Having a MAN on QAR500 a month?? He won't survive even a probation period on such diet.. :):) They need at least 2000 for food plus household (cleaning, washing, personal, kitchen stuff, etc.) - another 1000. Plus 1000 for the utilities. Plus 2000 for outings (restaurants and bars). Plus at least 1000 for the clothes and small entertaining (movies, beach, etc.)
This is more realistic calculation, Unless they want bury themselves in the Ezdan hole in remote Wakra, like someone has suggested.. but again, it's about a life style.. For me alone 20,000 wouldn't be enough.. forget about my wife (of husband in my instance, who needs alone about 40,000 to survive)
