Ok, so this is a Trick or Treat! challenge. First of all, you have to invite as many friends possible and post it here. The one who invites the most friends will get the mysterious secret from 'Minecraft Challenge!'. Same deal with the extra challenge from 'Minecraft Challenge' but there are 2 ways of getting the secret.

Second, is that you answer this mysterious riddle.

"Missing Money!

There were 3 boys checking into a hotel room. The guy at the coutner asks for $30 dollars altogether if they want a room. So they each gave $10. Later that day, the guy at the counter relizes that it was $24 not $30! So he called for the bellboy and said

'Give those boys there in Room 274 this extra $6 'cause I made a mistake in the price of the room.'

Then when the bellboy reached the room, he was a little greedy and took $2. He gave the boys $1 each. But wait, there is $6 not $5! $2 + ( $1 x $3) = $5! So where is the missing money? Is there a missing money? If there is who has it?"

Stumped on that one?
Try this one.

"If there is 3 people, and the each have 5 marbles, how do they jam 16 fans instead of 15? After all, the only have 15 altogether right?"

Or maybe something easier, like a maths sum

X5+2x15+X8=121

X=??
