Explanation:
To check if a number is divisible by 11, we can use the rule that states the difference between the sum of the digits at odd positions and the sum of the digits at even positions must be divisible by 11.
Let's calculate the difference for the given number, 2579 * 84:
Step 1: Calculate the sum of the digits at odd positions (starting from the right):
9 + 5 = 14
Step 2: Calculate the sum of the digits at even positions:
4 + 7 + 2 = 13
Step 3: Find the difference between the sums:
14 - 13 = 1
Now, if the difference is divisible by 11, then the number is divisible by 11. In this case, the difference is 1, which is not divisible by 11. Therefore, the number 2579 * 84 is not divisible by 11.
Conclusion:
The missing digit is not relevant in determining whether the number is divisible by 11. Therefore, the correct answer is option 'D' (None of these).
