Most populous capitals quiz

I just wanted to apologize for some spelling mistakes.1.Bagdad=Baghdad,

2.Pyongjang=Pyongyang,3.Teheran=

Tehran. This quiz is based on wikipedia so if some information is not correct in your opinion (like the fact that Delhi is not in that list) it is not my fault. But the spelling mistakes are caused of me not speaking english perfectly and the different pronounciation in my mother language german.
