Q: One of the activities in Grade 6 PE class is to get the average weight of the students from each group. In one of the groups, the average weight of five girls is 45 kg while the average weight of five boys is 55 kg. What is the average weight of the ten students from that group?
A: The sum of the weights of the five girls is 45 kg x 5 = 225 kg. The sum of the weights of the five boys is 55 kg x 5 = 275 kg. The sum of the weights of the ten students is 225 kg + 275 kg = 500 kg. Hence, the average weight of those ten students is 500 kg / 10 = 50 kg. The answer is 50.
