Five teams—A, B, C, D, and E—each consisting of 15 members, are going on expeditions to
five different locations. Each team includes members from three different skill sets: biologists,
geologists, and explorers. However, the number of members from each skill set varies by team
and each member has only one speciality. The total number of biologists, geologists, and explorers are equal.
The following additional information is available
• Every team has at least 2 members from each of the three skill sets.
• Teams C and D have 6 biologists each, and Team A has 6 geologists.
• Every team except A has more biologists than explorers.
• The number of explorers in each team is distinct and decreases in the order A, B, C, D,
and E.
