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?
Does this question need weight of each boy or the weight of two boys altogether when commenting the answer?
Which is correct answer in accordance to the question above👆 answer be 34 kg or 17kg
It would be the weight each - 17kg
Here is the process:
Mean = ∑x/n
15 = (2x+11)/3
Solve for x.
Based on the information given, the question asks for the weight of the other two boys combined.
To find the weight of the other two boys, we can subtract the weight of the third boy from the average weight of the three boys.
The average weight of three boys is 15 kg. Since two of them have the same weight, let's assume their weight is x kg.
We can set up an equation:
(x + x + 11) / 3 = 15
Combining like terms, we get:
(2x + 11) / 3 = 15
To solve for x, we can cross multiply and then solve for x:
2x + 11 = 45
2x = 34
x = 17
So, the weight of the other two boys combined is 17 kg, not 34 kg.
