One day I was visiting my sister in Boston and heard a bunch of kids yelling and playing in the yard ( yahd ).
I couldn't see the kids, and hadn't seen my sis for years so I asked her, "are all them kids yours, sis?"
"Hell no!", she laughed. "My kids are playing with their friends from three other families in the neighborhood, but ours is the biggest."
She explained to me that the Boyd's have a smaller number of kids, the Gilmore's have an even smaller number, and the Knight's have the smallest number of kids out of all of us.
"Interesting, how many kids all together?", I asked her.
"Let me sum it up like this, bro... there are fewer than 18 kids and the product of the numbers in the four families happens to be my house number which I texted to you for directions here."
Her house number...darn, phone's in the car in the text message.
I took out a piece of paper and started scribbling frantically.
"Sis, I need more information. Do the Knight's have more than 1 kid?"
My sister then told me,
"Bro actually you do not need any further info to figure this out, but I will tell you anyways."
As soon as she answered, I correctly told her the number of kids in each family, leaned over and hugged her goodbye, and left.
I figured this out based on the info provided, can you? Oh, you might need my sister's last name - Smith.
The Missing House Number What is it?
