SaveIn a prize draw, tickets are printed with 3-digit numbers from 001 to 999. Contestants pay to take a ticket at random. A major prize is awarded for all tickets where the product of the 3 digits on the ticket drawn is 8 and a minor prize is awarded when the product is 12. For example 143 wins a minor prize because 1 × 4 × 3 = 12.
What is the maximum number of major prizes which could be won?
