That is C grade website statistics, dont believe it. Actual foot falls/ticket sold for Sultan is coming around 3,58,00,000
Approx gross for the movie is INR 430,00,00,000/-, and average ticket prices for the movie is INR 120/-. Ticket prices were only hiked during weekend thats it, on all other days it was way too low.
With PK, Average Ticket prices were 190/-, that too for two weeks because of holidays. So PK stands nowhere near the success of Sultan and Bajrangi Bhaijaan.
BOI is pro Aamir Khan website, so they will keep promoting him no matter what. See the movies likes of Raja Hindustani, Rangeela, Lagaan they have increased all movie collections almost 30 to 50% and decreased the collections of other movies just to show aamir khan at top. So dont even visit that biased website. It is C Grade website without any authenticity or sources.
