Please guys can you help me this question#

The average weight of three boys is 15 kg.Two of them have the same weight and the third boy has weight of 11 kg. What is the weight of other two boys?

15kg-11kg=4 kg, then 4kg divide 2 =2 kg

Once you get an answer, make sure it is reasonable. How can a boy weigh 2kg? And,...

if their average weight is 15, then the sum of their weights is 3*15 = 45
Now you can say
45-11 = 34
now the other two boys weigh 34/2 = 17kg

11,17,17 have an average of 15

Does this question need weight of each boy or the weight of two boys altogether when commenting the answer?

To solve this question, we need to understand the given information. Let's break it down step by step:

1. The average weight of three boys is 15 kg.
- This means that if we add up the weights of all three boys and divide by 3, we will get the average weight of 15 kg.

2. Two of the boys have the same weight.
- Let's call the weight of these two boys "x".

3. The weight of the third boy is 11 kg.
- Let's call the weight of this boy "y".

Now, let's calculate the weights of the other two boys:

Step 1: Find the total weight of the three boys.
- We know that the average weight is 15 kg, so the total weight of the three boys is 15 kg multiplied by 3, which is 45 kg.

Step 2: Account for the weight of the third boy.
- The weight of the third boy is given as 11 kg. To find the combined weight of the other two boys, we subtract 11 kg from the total weight (45 kg) as follows: 45 kg - 11 kg = 34 kg.

Step 3: Divide the combined weight equally between the other two boys.
- Since we know that the weight of the two boys is the same (let's call it "x"), we can divide the combined weight of 34 kg equally between them. So each of them would have a weight of 34 kg divided by 2, which is 17 kg.

Therefore, the weight of the other two boys is 17 kg each.
