Q6. Alok and Bhanu play the following min-max game. Given
the expression
N = 9 + 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 the 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
a) 0 b) 27 c) 18 d) 20
The Q's concept is
same but the equation of N's is changing.
Q7. Alice and Bob play the following coins-on-a-stack game.
20 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 (0 = i = 20). 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 coinis the third coin from the top. Then
a) In order to win, Alice's first move should be a 1-move.
b) In order to win, Alice's first move should be a 0-move.
c) In order to win, Alice's first move can be a 0-move or a
1-move.
d) Alice has no winning strategy.
Ans: d

predicting the winner of each match with amazing success. It is rumored that in
a match between 2 teams A and B, Paul picks A with the same probability as A's
chances of winning. Let's assume such rumors to be true and that in a match

winning the game. What is the probability that Paul will correctly pick the
winner of the Ghana-Bolivia game?
a)1/9 b)4/9 c)5/9
d)2/3
Ans: 5/9
