What three numbers have an average of 200?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 200. This means if we add these three numbers together and divide by 3, we should get 200.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 200 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 200 * 3 = x + y + z
- So, the sum of our three numbers should be: 600
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 600.
Solution 1:
200, 200, 200
Verification:
(200 + 200 + 200) / 3 = 600 / 3 ≈ 200
This solution is correct!
Solution 2:
200, 200, 200
Verification:
(200 + 200 + 200) / 3 = 600 / 3 ≈ 200
This solution is correct!
Solution 3:
298, 249, 53
Verification:
(298 + 249 + 53) / 3 = 600 / 3 ≈ 200
This solution is correct!
Solution 4:
571, 7, 22
Verification:
(571 + 7 + 22) / 3 = 600 / 3 ≈ 200
This solution is correct!
Solution 5:
488, 81, 31
Verification:
(488 + 81 + 31) / 3 = 600 / 3 ≈ 200
This solution is correct!
Explanation:
As you can see, there are many possible solutions. We can find more by:
- Choosing any two numbers
- Subtracting their sum from 600 to get the third number
Remember:
- The numbers don't have to be whole numbers.
- They can even be negative (although that might not make sense in some real-world contexts).
- The order of the numbers doesn't matter for the average.
