Passage

Directions: Study the following information and answer the question. Players are selected for Judo based on their body weights from the following 10 weight groups: 1. (48 kg – 52 kg) 6. (68 kg – 72 kg) 2. (52 kg – 56 kg) 7. (72 kg – 76 kg) 3. (56 kg – 60 kg) 8. (76 kg – 80 kg) 4. (60 kg – 64 kg) 9. (80 kg – 84 kg) 5. (64 kg – 68 kg) 10. (84 kg – 88 kg) The average weight of the players after selecting one player from each group is 68 kg. If one of the players (named S) leaves the team, their average weight comes down to 66.5 kg.

What is the average weight of all the players taken together?

The problem provides the average weight of the selected team, which consists of only one player from each of the 10 groups, making their total weight 680 kg. It does not provide any information about the number of players or the weights of the remaining players in the various groups. Without the total number of players and their total weight, calculating the overall average is impossible. Therefore, the average weight cannot be determined.
