To celebrate its grand opening, a store is giving customers gift certificates.
Every 8th customer gets a $50 gift certificate, which means that the 16th customer gets a $50 gift certificate.
Every 6th customer gets a $10 gift certificate, which means that the 12th customer gets a $10 gift certificate.
Regardless of the gift certificates they get, every 6th customer will be the first to get 2 gift certficates because it takes lesser number of customers or turns to get another gift certificate.
Hence, every 6th customer gets 2 gift certificates first.
