IBPS SO Prelims Exam Model Paper 1

Formula:
Revenue = (Price of ticket) (Number of viewers)
Calculation:
Let the price of the ticket before and after be p and 0.75p respectively.
Let the number of viewers before and after be x and 1.3x respectively.
Revenue before = px
Revenue after = (0.75p)(1.3x) = 0.975px
According to the question,
Difference in revenue = px – (0.975px) = 0.025px
⇒ 0.025px = 325
⇒ px = 13000
∴ we cannot find the initial price of ticket.
