The average of the two digit numbers, which remain the same when the digits interchange their position is:
Approved Tutor Answer10 Months agoThe two-digit numbers that remain the same when their digits are swapped are known as palindromic numbers. In this case, the only two-digit palindromic numbers are 11, 22, 33, 44, 55, 66, 77, 88, and 99.
To find the average of these numbers, we first need to add them together:
The sum is:
11 + 22 + 33 + 44 + 55 + 66 + 77 + 88 + 99 = 495
There are a total of 9 two-digit palindromic numbers.
Now, we divide the total sum by the number of values:
Average = Total Sum / Number of Values = 495 / 9 = 55
Thus, the average of the two-digit numbers that remain the same when their digits are interchanged is 55. Therefore, the correct answer is C. 55.
