Alice and Bob play the following coins-on-a-stack game. 100 coins are stacked one above the other. One of them is a special (gold) coin and the rest are ordinary coins. The goal is to bring the gold coin to the top by repeatedly moving the topmost coin to another position in the stack. Alice starts and the players take turns. A turn consists of moving the coin on the top to a position i below the top coin (for some i between 0 and 100). We will call this an i-move (thus a 0-move implies doing nothing). The proviso is that an i-move cannot be repeated; for example once a player makes a 2-move, on subsequent turns neither player can make a 2- move. If the gold coin happens to be on top when it's a player's turn then the player wins the game. Initially, the gold coin is the third coin from the top. Then O In order to win, Alice's first move can be a 0-move or a 1-move. O In order to win, Alice's first move should be a 1-move. O In order to win, Alice's first move should be a 0-move. O Alice has no winning strategy. 8. The IT giant Tirnop has recently crossed a head count of 150000 and earnings of S7 billion.

In 1911, a French physicist Paul Langevin, devised a thought experiment based on Einstien's Special Relativity. In the experiment, a person makes a journey into space at nearly the speed of light and comes back to earth. He finds that he has aged five times less than his twin who stayed back on earth for 40 years. This is popularly known as the Twin Paradox. Now, consider the case of Hansel and Gretel, who are not twins. 9 years ago, Hansel was twice as old as Gretel. If they journey into space, an atomic clock assists in logging the start time of their journey accurately.

A result of global warming is that the ice of some glaciers is melting. 12 years after the ice disappears, tiny plants, called lichens, start to grow on the rocks. Each lichen grows approximately in the shape of a circle. The relationship between the diameter of this circle and the age of the lichen can be approximated with the formula: d =5* (t -12) for t >12, where d represents the diameter of the lichen in millimeters, and t represents the number of years after the ice has disappeared. Using the above formula, calculate the diameter of the lichen, 49 years after the ice has disappeared. O 185 O 12 O 245 O 233 24.

It is most common in elders but is not caused by ageing. In studying the brains of Alzheimer and non-Alzheimer patients it has been found that those diagnosed with Alzheimers have less brain tissue compared to non-Alzheimer patients. The results show a correlation between a decrease of brain tissues with an increase in abnormal protein deposits in the brain. Therefore one hypothesis for the cause of Alzheimers is due to the abnormal protein deposits. Which of the following weakens the conclusion above? O Autopsies of Alzheimer patients have shown that deterioration of intellectual faculties is often associated with emotional disturbance and personality changes. O The brains of Alzheimer patients have been found to produce an unusual substance which decomposes protein. O People who are in their sixties are more likely to develop Alzheimers than any other age group. O Laboratory research shows that when people age, their brain tissues degenerate. 94.1/2 of a number is 6 more than 1/6 of the same number. What is the number?

However consumers are unable to take advantage of this finding as fiber content is usually not listed on the Nutrition Information label on food packages. Therefore as a further precaution in preventing heart disease, the government must regulate food industries to include the fiber content on the Nutrition Information label on food packages. Which of the following weakens the argument above? O In addition to high fiber food, low fat food has also been proven to prevent heart disease. O Having more high fiber food also lowers the risk of getting rectum cancer. O Most consumers that buy packaged food do not pay attention to the Nutrition Information label on the packages. O High fiber foods normally have low content of protein. 96.In how many ways can 4 letters be posted in 2 post boxes, if any number of letters can be posted in all of the two post boxes?
