Jampros wants to manufacturer 7 different varieties of jam, each a combination of three different fruits. They have 7 different kinds of fruit to choose from: Juju, Apricot, Mango, Peach, Raspberry, Orange, and Strawberry. They want every possible pair of fruits to appear in exactly one of the varieties and they also require that any 2 varieties have exactly one fruit in common. Can you help Jampros by listing 7 different varieties of jam that satisfy all of these requirements?
