Dave wanted to enter a club but a password was required.
So he waited to listen.
A woman appeared the bouncer said 1 and she replied 3, she entered.
A man came the bouncer said 3 the man replied with 5, he entered.
Dave came to the door the bouncer said 5 Dave said 7 but it was wrong.
How?
The password seems to be related to the number of letters in the number that the bouncer says, rather than the number itself.
When the bouncer says “1,” the woman replies with “3,” which has three letters.
When the bouncer says “3,” the man replies with “5,” which has five letters.
Therefore, when the bouncer says “5,” the password should be 4 as number of letters in 5.
However, Dave responds with “7,” Therefore, his response is incorrect, and he cannot enter the club with that
