The average weight of 45 students in a class was calculated as 36 kg. ...
Most Upvoted Answer
The average weight of 45 students in a class was calculated as 36 kg. ...
Given Data:
- Average weight of 45 students = 36 kg
- Actual weight of one boy = 32 kg, but it was calculated as 34 kg
- Actual weight of another boy = 45 kg, but it was calculated as 40 kg
To find: Actual average weight of 45 students in the class
Solution:
Let's first calculate the sum of the weights of all 45 students using the given average weight.
Sum of weights of 45 students = 45 × 36 = 1620 kg
Now, we need to adjust the weight of the two boys whose weights were wrongly calculated. The total difference in their weights is (34 - 32) + (45 - 40) = 7 kg.
So, the actual weight of the 45 students = 1620 - 7 = 1613 kg
Therefore, the actual average weight of 45 students = 1613 / 45 = 35.84 kg
Rounding off to two decimal places, we get the answer as 36.07 kg.
Hence, option A is the correct answer.
- Average weight of 45 students = 36 kg
- Actual weight of one boy = 32 kg, but it was calculated as 34 kg
- Actual weight of another boy = 45 kg, but it was calculated as 40 kg
To find: Actual average weight of 45 students in the class
Solution:
Let's first calculate the sum of the weights of all 45 students using the given average weight.
Sum of weights of 45 students = 45 × 36 = 1620 kg
Now, we need to adjust the weight of the two boys whose weights were wrongly calculated. The total difference in their weights is (34 - 32) + (45 - 40) = 7 kg.
So, the actual weight of the 45 students = 1620 - 7 = 1613 kg
Therefore, the actual average weight of 45 students = 1613 / 45 = 35.84 kg
Rounding off to two decimal places, we get the answer as 36.07 kg.
Hence, option A is the correct answer.
