Math Is Fun Forum

It has been one month since I started, and not once have I formally introduced myself to anyone...
I hope its not yet too late...

Hello, I am JohnnyReinB, but you can call me Johnny. i am from the Philippines, and I am 13 years old.

I came upon mathisfunforum when I was researching for math and found Mathisfun.

For this whole month I joined, I found this site very fun! And i really thank the creator of this site...

There, Like I said, I hope its not too late...

I had this idea before. This is a sort of Sherlock Holmes mystery where you have to guess how the detective figured out the mystery. Pls post with hidetags if you have the answers. For those who are very observant, they'll get the answers pretty quickly, since the stories have all the facts needed to give the answer. Good Luck!

The Nhoj Case Files #1: The Case of The Pearly Diamonds

The afternoon soon gave way to night when I was called to HQ. It seems that the Pearly Shells, a highly renowned souvenir franchise, has housed a group of diamonds, hidden in the shells.

" Thank God you're here!" exclaimed Chief. "This case is cleaner than any I've ever faced before!"

"Got any suspects?" I asked.

"Yeah, three. The manager of the store, forty-nine years old, 183 cm tall, slightly overweight.. Came from California.

" Then there's the clerk, thirty-five years old. Hired recently. 142 cm tall. He's from downtown. Arrested 10 years ago for petty theft.

" And lastly, a regular. Got arrested 5 years ago for robbery. 280 cm tall, lean. He wasn't convicted, though."

After the talk with the chief, I went down to the Pearly Shells. The store was famous for its beautiful shells, the costly ones with mother-of-pearl coating. Inside, it looked like a seashore, similar to the one outside.

However, the room where the diamonds were found was small, 5 feet in height.  Boxes were stacked in one corner. Apart from the ceiling, which was riddled with cobwebs, the room was clean, just like what the chief said. No fingerprints, no hair strands, no luck.

Back in HQ, I was still wondering about the case. Then I remembered what chief said. I knew, this case is as good as solved!

In this first one, you have to figure out who was the smuggler...Good Luck!

Sometimes, It is the subtle mistakes that make the biggest mistakes

Got any good contradicting equations? Maybe people could donate such, and others would try to find out what is wrong...

Let's start easy:

(this was in our exam, I thought it was pretty easy for us, until I asked my classmates what they answered...)
