enoyed the quiz, but I can't help pointing out some errors in the quiz:

Aishwarya Rai was never Miss Universe. She was Miss World.

The question on the average length of the Sari ...6.5 , 9.5, etc are the choices...but what is the unit of measure...metres? yards?
Most saris are sold in 5.5 metre length all over India.

the word Chatni is a "hindi" word..there is no language called "hindu".

Finally...an arguable point:
There are definitely movies that have been much more successful than Devdas in Indian film history. Devdas has the dubious distinction of being one of the most expensive films in bollywood history.
