Solution

Tickets are being sold for a football match at the school. The number of student tickets sold is 50 less than the parent tickets and the parent tickets sold are twice as many as the student tickets.

Let x be the number of student tickets sold. Then the number of parent tickets sold is 2x. Now, since the number of student tickets sold is 50 less than the parent tickets, hence x = 2x-50 or, 2x-x = 50. Therefore, x = 50. Thus, 50 student tickets and 100 parent tickets were sold.
