I have recently asked a question (The original did not turn up in my search): Show that there are infinitely many powers of two starting with the digit 7 which was marked as a duplicate of: Starting digits of $2^n$..
There was much more activity on the duplicate that I have asked and the answers on it seem to be more complete and comprehensive as compared to the original. What would happen to these answers (I assume they will be deleted)?
TL;DR What would be the actions taken if a duplicate has a better set of answers as compared to the original?
