A hare and a tortoise have a race along a circle of 100 yards diameter. The tortoise goes in one direction and the hare in the other. The hare starts after the tortoise has covered 1/5 of its distance and that too leisurely. the hare and tortoise meet when the hare has covered only 1/6 of the distance. by what factor should the hare increase its speed so as to tie the race?

Planet Fourfe resides in 4-dimensional space and thus the currency used by its residents are 3-dimensional objects. the rupee notes are cubical in shape while their coins are spherical. however the coin minting machinery lays out some stipulations on the size of the coins. A. The diameter of the coins should be at least 4mm and not exceed 8mm. B. Given a coin, the diameter of the next larger coin is at least 50% greater. C. The diameter of th coin must always be an integer. you are asked to design a set of coins of different diameters with these requirements and your goal is to design as many coins as possible. How many coins can you design?

Given a collection of points P in the plane a 1-set is a point in P that can be separated from the rest by a line; i.e the point lies on one side of the line while the others lie on the other side. The number of 1-set of P is denoted by n1(p). The maximum value of n1(P) over all configurations P of 5 points in the plane is

A result of global warming is that the ice of some glaciers is melting. 16 years after the ice disappears, tiny plants, called lichens, start to grow on the rocks. ecach 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=18*(t-16) for t > 16, where d represents the diameter of the lichen in millimeters, and t represents the muber of years after the ice has disappeared. Using the above formula, calculate the diameter of the lichen, 33 years after the ice has disappeared.

Alice and Bob play the follwoing coins oin a stack game. 100coins 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 up 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 impklies doing nothing). The proviso is that an i move canot be repeated. for example once a player makes 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 turn then the player wins the game. Initially, the gold coin is the thiurd coin from the top.
In order to win, alice,s first move should be a 0-move
in order to win, alice,s first move can be a 0-move or a 1-move
in order to win, alice,s first move should be a 1-move
alice has no winning strategy

For the FIFA World cup, Paul the octopus has been predicting the winner of each match with amazing success. It is rumored that in a match between 2 teams A and B, Pul picks A with the same probability as A,s chances of winning. Let,s assume such rumors are to be true and that in a match Ghana and Bolivia, Ghana the stronger team has a probability of 6/7 of winning the game. What si the probability that paul will correctly pick the winner of the Ghana Boliovia game?

Alok and Bhanu play the following min max game. Given the expression N= 39+X+Y-Z, where X,Y and Z are variables representing single digits (0 to 9), Alok would like to maximize N while Bhanu would like to minimize it. Towards this end, Alok chooses a single digit number and Bhanu substitutes this for a variable of her choice (X, Y or Z). Alok then chooses next value and Bhanu, the variable to substitute the value. Finally alok proposes the value for the remaining variable. Assuming both play to their optimal strategies, the value of N at the end of the game would be
