Answer 1

Let the number of Rs 15 tickets be x

The number of Rs 30 tickets will be (500 - x)

Solve x:

15x + 30(500 - x) = 12000

15x + 15000 - 30x = 12000

15x = 3000

x = 200

Find the tickets:

Rs 15 tickets = x = 200

Rs 30 tickets = 500 - 200 = 300

Answer: 200 of the Rs 15 tickets and 300 of the Rs 30 tickets were sold.
