Verified Answer
The average of 8 numbers 12, 19, 23, 7, ‘x’, 9, 26 and 13 ...
12 + 19 + 23 + 7 + x + 9 + 26 + 13 = 16 × 8
109 + x = 128
x = 128 – 109 = 19
Hence, Option D is correct.
109 + x = 128
x = 128 – 109 = 19
Hence, Option D is correct.

The average of 8 numbers 12, 19, 23, 7, ‘x’, 9, 26 and 13 ...
Given Data:
- List of numbers: 12, 19, 23, 7, 'x', 9, 26, 13
- Average of the numbers: 16
Let's Solve for 'x':
Step 1: Find the total sum of the numbers
Sum of the numbers = 12 + 19 + 23 + 7 + x + 9 + 26 + 13
Sum of the numbers = 109 + x
Step 2: Calculate the average
Average = Sum of the numbers / Total count of numbers
16 = (109 + x) / 8
Step 3: Solve for 'x'
16 * 8 = 109 + x
128 = 109 + x
x = 128 - 109
x = 19
Therefore, the value of 'x' is 19.
Conclusion:
The value of 'x' is 19, which means the correct option is 'None of these'.
