The average weight of 24 students is 35 kgs. If the weight of teacher ...
Given Data:
- Average weight of 24 students = 35 kgs
- Increase in average weight when teacher's weight is added = 400 gms
Calculating the total weight of 24 students:
- Total weight of 24 students = Average weight * Number of students
- Total weight of 24 students = 35 kgs * 24 = 840 kgs
Calculating the new average weight:
- Let the weight of the teacher be x kgs
- New total weight = Total weight of students + Weight of teacher
- New total weight = 840 kgs + x kgs
- New average weight = (Total weight of students + Weight of teacher) / (Number of students + 1)
- New average weight = (840 + x) / 25
Given:
- Increase in average weight when teacher's weight is added = 400 gms
- 400 gms = 0.4 kgs
Equation:
- New average weight - Old average weight = 0.4
- (840 + x) / 25 - 35 = 0.4
- (840 + x) / 25 = 35.4
- 840 + x = 25 * 35.4
- x = 885 - 840
- x = 45 kgs
Conclusion:
- The weight of the teacher is 45 kgs.
- Average weight of 24 students = 35 kgs
- Increase in average weight when teacher's weight is added = 400 gms
Calculating the total weight of 24 students:
- Total weight of 24 students = Average weight * Number of students
- Total weight of 24 students = 35 kgs * 24 = 840 kgs
Calculating the new average weight:
- Let the weight of the teacher be x kgs
- New total weight = Total weight of students + Weight of teacher
- New total weight = 840 kgs + x kgs
- New average weight = (Total weight of students + Weight of teacher) / (Number of students + 1)
- New average weight = (840 + x) / 25
Given:
- Increase in average weight when teacher's weight is added = 400 gms
- 400 gms = 0.4 kgs
Equation:
- New average weight - Old average weight = 0.4
- (840 + x) / 25 - 35 = 0.4
- (840 + x) / 25 = 35.4
- 840 + x = 25 * 35.4
- x = 885 - 840
- x = 45 kgs
Conclusion:
- The weight of the teacher is 45 kgs.
