## Unfortunate Robber - 11/02/12 03:05 AM

Found this. Kinda neat!

On Monday, a backward robber walked into a drugstore, pointed the gun at himself

and handed the storekeeper half of the gold coins in his bag.

The storekeeper, seeing his chance to make a handsome profit, demanded that the

robber should also give him one third of the coins left in the bag.

After counting out this number, the robber had a fit of belligerence and decided

to give one half of the coins instead of one third.

Exactly the same thing happened on Tuesday, Wednesday, Thursday and Friday:

the robber walking into the store with the same three-digit square number

of coins in his bag.

By the end of the week, the storekeeper had gained a cubic number of coins.

How many coins did the storekeeper receive?

No need to show your work; you can if you wish!
