Answer: There are 120 student tickets and 360 adult tickets.
Step-by-step explanation:
Let the number of student's ticket be 'x'
Let the number of adult ticket be '3x'
Total number of tickets = 480
So, According to question, we get that
[tex]x+3x=480\\\\4x=480\\\\x=\dfrac{480}{4}\\\\x=120[/tex]
So, there are 120 student's ticket and [tex]3x=3\times 120=360[/tex] adult's tickets.
Hence, there are 120 student tickets and 360 adult tickets.
