Junior Level

We have 9 cells in a horizontal row. There is a coin placed in each cell. The cells marked by an O have the coins faced up. The cells marked by an X have the coins faced down.
Pick a face-up coin and flip all the coins to its left. Repeat until all the coins are flipped. How many times should you flip the coins until they are all facing downwards (All Xs)?
We have 12 cards, each containing a number from 1 to 12.
We remove 3 cards so that adding 3 random cards out of the remaining 9 cards will not give a total of 12. What are the values of these 3 removed cards, such that their sum is the maximum possible?
A shaded rectangle is inside of a regular decagon. The rectangle has an area of 100cm². Find the area of the regular decagon.

Senior Level

We wrap a ribbon around a cube of 3cm on one of the sides, as showed in the diagram. When the ribbon is wrapped until it forms a loop around the cube, what is the area of the unwrapped cube?
We have 13 cards, each containing a number from 1 to 13. A teacher picked 2 cards from these 13. He then informed student A the product of the numbers on these 2 cards, student B the sum, and student C, the difference. The students then had the following conversation:
A: I don’t know the answer.
B: Me neither.
C: I have got to give up.
A: I don’t know yet.
B and C: We don’t know too.
What are the numbers of these 2 cards?
Consider an integer which fulfils the following condition:
“Adding all the digits in the integer, and multiplying the sum by itself for several times will result in the same integer”
For example, 512 is such an integer:
1. 5 + 1 + 2 = 8
2. 8 x 8 x 8 = 512
Find 3 such integers.
