Question

One digit in each of these identification numbers of a postal money order is smudged. Can you recover the smudged digit, indicated by a Q, in each of these numbers?

a) Q1223139784
b) 6702120Q988
c) 27Q41007734
d) 213279032Q1

Answer 1

Without the specific algorithm used to calculate the check digit for the identification numbers on postal money orders, it is not possible to accurately recover the smudged digits in the provided sequences.

Step-by-step explanation:

The identification numbers on postal money orders are likely secured with a check digit, which is a form of redundancy check used for error detection. This check digit is typically calculated by a specific algorithm. Without knowing the exact algorithm, we can’t determine the correct missing digit with certainty. So, due to the insufficient information given in the student question, I regret that I am unable to provide the correct smudged digit for each of the postal money order identification numbers given: (a) Q1223139784, (b) 6702120Q988, (c) 27Q41007734, (d) 213279032Q1.
