What three numbers have an average of 201?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 201. This means if we add these three numbers together and divide by 3, we should get 201.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 201 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 201 * 3 = x + y + z
- So, the sum of our three numbers should be: 603
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 603.
Solution 1:
201, 201, 201
Verification:
(201 + 201 + 201) / 3 = 603 / 3 ≈ 201
This solution is correct!
Solution 2:
201, 201, 201
Verification:
(201 + 201 + 201) / 3 = 603 / 3 ≈ 201
This solution is correct!
Solution 3:
591, 1, 11
Verification:
(591 + 1 + 11) / 3 = 603 / 3 ≈ 201
This solution is correct!
Solution 4:
563, 30, 10
Verification:
(563 + 30 + 10) / 3 = 603 / 3 ≈ 201
This solution is correct!
Solution 5:
339, 258, 6
Verification:
(339 + 258 + 6) / 3 = 603 / 3 ≈ 201
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 603 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.
