Sure, let's work out the average weight of the four children step-by-step.
1. List the weights of the children:
- Mona: 34.0 kg
- Kashif: 36.2 kg
- Aslam: 35.8 kg
- Insia: 40.0 kg
2. Calculate the sum of all the weights:
- First, add Mona's weight and Kashif's weight: [tex]\(34.0 + 36.2 = 70.2\)[/tex]
- Next, add Aslam's weight to the running total: [tex]\(70.2 + 35.8 = 106.0\)[/tex]
- Finally, add Insia's weight to that total: [tex]\(106.0 + 40.0 = 146.0\)[/tex]
So, the total sum of the weights is [tex]\(146.0\)[/tex] kg.
3. Count the number of children:
- There are four children.
4. Calculate the average weight:
- To find the average weight, divide the total sum of the weights by the number of children:
[tex]\[
\text{Average weight} = \frac{\text{Total sum of weights}}{\text{Number of children}} = \frac{146.0}{4} = 36.5
\][/tex]
So, the average weight of the four children is [tex]\(36.5\)[/tex] kg.
