Question

Read the following passage carefully.

Mas, Marks: 20



In 1974 Hungarian professor of architecture and sculpture Erno Rubik was trying to solve a structural mechanism problem and ended up creating a puzzle that continues to fascinate purlins across the world. It was an object that was not supposed to be possible. The cube was solid but could be twisted and turned without breaking or falling apart. Originally meant to be a teaching tool the 3-D cube remains the world's top selling and best loved puzzle to date, with more than 350 million cubes sold since 1980.

2) The cube has six different coloured faces

white, red, blue, orange, green and yellow and each

face has nine little squares. In currently sold models, white is opposite yellow, blue is opposite

green, and orange is opposite red. The red, white and blue faces are arranged in that order in a

clockwise arrangement.

(3) The cube can be taken apart without much difficulty, typically by rotating the top layer by 45anle then prying one of its edge cubes away from the other two layers. Consequently it is a simple process to "solve" a cube by taking it apart and reassembling itin a saved state.

(4) To solve the puzzle, the sides of the cube have to be rotated in such a way that each face contains only one colour. In most competitions, puzzlers solve the puzzle using both their hands but there are also competitions which involve solving the cube with one hand, using the feet or even blindfolded! Now, you can solve the puzzle on your computer, too. However, the greatest thrill comes from cracking the puzzle in the shortest possible time.
