Is 4/10 a good score for India?

I chanced upon the July 9th issue of Newsweek at my doctor's office and guess what I read something that needs to be here...It had the list of top 10 cities in the world with the worst air pollution problems based on a survey by the World Bank and here they are

1) Cairo
2) Delhi
3) Kolkata
4) Tianjin
5) Chongqing
6) Kanpur
7) Lucknow
8) Jakarta
9) Shenyang
10) Zhengzhou
