Mystery Pic and Lenny Conundrum

Linae, the Kougra from Shenkuu, went shopping for Kou-jong tiles at the local toy shop the other day. The kou-jong tiles were on sale for only 28 Neopoints each.

However, she got it in her head that, for good luck, the total amount of Neopoints she must spend must be a number where all of the digits are the same.

With that in mind, what is the minimum number of tiles she must buy?

(more…)

Problem

Old Cap’n Bloodhook, the captain of The Black Pawkeet, needed to pack away some of his hoarded dubloons. “I’ll tell you what,” he said, “if ye can help me figure out how many dubloons can fit into this tray, I’ll be givin’ ye a reward!”

So the tray is perfectly square, and just big enough to fit 10 dubloons along one side.

So, without overlapping any dubloons, what is the maximum number of dubloons that can fit in the tray?

Solution

Anyone who had heard of multiplication shouldn’t have a problem with this one. I’m thinking they make this to give the younger players a chance of winning.

Edit

Heh, heh, in my rush, I forgot about the extra spaces between the dubloon that can be used to stack extra ones in.  Oh well, next LC then.

I really don’t know if I should write a lenny post at all, given the very detailed explanation in the forum.  So I’ll stick to conundrums that are not already explained from now on.  *point to Lenny Forum link*
