The sale of a cinema tickets is increased by 13\(\frac{1}{3}\)% and price of ticket increased by 20%. Find the percentage change in the revenue.
Answer & explanation
Correct answer: option 4
Original : Changed
Tickets Sold = 15 : 17 [13\(\frac{1}{3}\)% = \(\frac{2}{15}\)]
Price = 5 : 6 [20% = \(\frac{1}{5}\)]
————————————
[Revenue = Ticket Sold × Price) = 75 : 102
25 : 34
Difference = 34 - 25 = 9
Change % = \(\frac{9}{25}\) × 100 = 36%
