C) 83 %
Step-by-step explanation:
Let the sale of number of cinema tickets be x and the price of each ticket be Rs y.
Total revenue colleced = Rs xy
Number of seats are increased by 57% ⇒ 1.57 x
Price of each ticket is increased by 16% ⇒ 1.16y
Total revenue collected = 1.57x × 1.16y = 1.8212 xy
Increased revenue = 1.8212 xy - xy = 0.8212 xy
Percentage increase = (0.8212 xy) / (xy) × 100 = 82.12 %.
(note :- 82.12 % = 83 % )
