Its very simple calculation.
Secret superstar released in china 20000 screens. Now BOI says that bajrangi bhaijaan released 8000 screens in china and promotion charge 35 cr so according to this secret super star 90 cr approx.
Secret superstar business in china approx 750 cr so share is 25% for distributors
750*25/100 = 187.50 cr
Now promotion charge = 90 cr approx
So profit = 100 cr approx
Same apply for bajrangi bhaijaan.
Ab china ke baare me BOI se jyada knowledge aamir fans ko ho to wo apni site khol le. Lagta hai aamir fans bajrangi ki safalta ko pacha nahi pa rahe hai.
