#### 18. 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 tomaximize N while Bhanu would like to minimize it. Towards this end, Alok chooses a singledigit number and Bhanu substitutes this for a variable of her choice (X, Y or Z). Alok thenchooses the next value and Bhanu, the variable to substitute the value. Finally Alok proposesthe value for the remaining variable. Assuming both play to their optimal strategies, the valueof N at the end of the game would be.

#### 19. Alice and Bob play the following coins-on-a-stack game. 20 coins are stacked one abovethe other. One of them is a special (gold) coin and the rest are ordinary coins. The goal is tobring the gold coin to the top by repeatedly moving the topmost coin to another position inthe stack.Alice starts and the players take turns. A turn consists of moving the coin on the topto a position i below the top coin (0 = i = 20). We will call this an i-move (thus a 0-moveimplies doing nothing). The proviso is that an i-move cannot be repeated; for example once aplayer makes a 2-move, on subsequent turns neither player can make a 2-move. If the goldcoin happens to be on top when it's a player's turn then the player wins the game. Initially, thegold coins 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.

#### 34. In a country x we are having diff types of coins ranging from 64...512. All coins havingdifferent integral value the difference between two coins comes out to be 50% more than theformer coin. Then how many coins can be made?

Ans : 6 coins

Sol.64

64*1.5=96

96*1.5=144

144*1.5=216

216*1.5=324

324*1.5=486

Then total coin will be 6
