In a movie hall, there are three categories of seats: Diamond, Gold and Silver. On a week day, the prices per ticket in these categories are ₹500, ₹300 and ₹200, respectively. But on weekends, the prices are raised to ₹800, ₹500 and ₹300, respectively. There are exactly 10 Diamond seats and the number of Silver seats is double the number of Gold seats. If the hall goes house full in all the shows, which of the following is the excess earning made per show on a weekend?
- A₹20,000
- B₹23,000
- C₹26,000
- D₹30,000
Explanation
The weekend price premium per ticket is Rs 300 for Diamond (800-500), Rs 200 for Gold (500-300) and Rs 100 for Silver (300-200). The keyed answer of Rs 23,000 implies 50 Gold seats and hence 100 Silver seats (double the Gold seats): 10x300 + 50x200 + 100x100 = 3,000 + 10,000 + 10,000 = Rs 23,000. Note the question stem does not state the number of Gold seats; the count of 50 is implied by the official answer.
