To find the mean weight of the remaining students, we can break down the problem using the information provided.

Total Mean Weight Calculation
The total mean weight of all 15 students is given as 110 kg. Thus, we can calculate the total weight of all students:
- Total weight of all students = Mean weight × Number of students
= 110 kg × 15
= 1650 kg

Mean Weight of Groups of Students
Next, we will analyze the weights of the groups of students:
- For the first group of 5 students with a mean weight of 100 kg:
Total weight = 100 kg × 5 = 500 kg
- For the second group of 5 students with a mean weight of 125 kg:
Total weight = 125 kg × 5 = 625 kg

Total Weight of the First Two Groups
Now, we can find the combined weight of the first two groups:
- Combined weight of first two groups = Weight of first group + Weight of second group
= 500 kg + 625 kg
= 1125 kg

Weight of Remaining Students
To find the weight of the remaining 5 students, we subtract the combined weight of the first two groups from the total weight:
- Weight of remaining students = Total weight - Combined weight of first two groups
= 1650 kg - 1125 kg
= 525 kg

Mean Weight of Remaining Students
Finally, we calculate the mean weight of the remaining 5 students:
- Mean weight of remaining students = Weight of remaining students ÷ Number of remaining students
= 525 kg ÷ 5
= 105 kg
Thus, the mean weight of the remaining students is **105 kg**.
