Kids presents Brainbenders — fun and interesting mental exercises to make you think and go “hmmm … ”
The passwords
A man worked for a high-security institution, and one day he went in to work only to find that he could not log in to his computer terminal.
His password wouldn’t work. Then he remembered that the passwords are reset every month for security purposes. So he went to his boss and they had this conversation:
Man: “Hey, boss, my password is out of date.”
Boss: “Yes, that’s right. The password is different, but if you listen carefully you should be able to figure out the new one: It has the same amount of letters as your old password, but only four of the letters are the same.”
Man: “Thanks boss.”
With that, he went and correctly logged into his station.
What was the new password?
BONUS: What was his old password?
Here’s the answer to last week’s Brainbender:
The card collector
The card should go in the sixth spot. Adding all the digits of a 10-base number together will give you a number from 1 to 9, which corresponds to the lowest digit in the 9-base system to which you’re converting.
In other words, 2+5+8 = 15, and 1+5 = 6. The card goes in the sixth spot.
