Question

A man worked at a high security institution. The man tried
to log into his computer, but the computer denied the
password. He then remembered that the passwords to the
computers were reset every month for security reasons. He
called his boss for his new password.
The man said, "Boss, my old password is out of date.
The boss said, 'Yes, it is. The new password is different,
but if you listen closely you will be able to figure out the
new one. Your new password has the same amount of letters
as the old one, and four of the letters are the same.'
The man then logged into his computer with no trouble:
what was the new password? What was his old password?​

Answer 1

Answer:

his old password may be the new password also.
