alok n bhanu play the following min max game
N=9+X+Y-Z
so,wer x,y,z,are variables representing single digits(0..9)alok would like to maximise N while bhanu would like to minimise the N towards the end.alok choose a single digit number and bhanu substitutes this for a variable of her own choice (X,Y,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 the N at the end of the game would be??

20.. always remember the maximum no. of Y-Z in this game can be 2. (how it is derived, if any one interested to know, i shall post it later. how i just giv the solution) so at the last chance when alok proposes its value. he proposes 9. so the value would be 9+9+2=20

ans is 18.
Alok Maximize while Bhanu Minimize.
Alok Choose a single digit (0-9) but he wants to max so he take 9.
Bhanu like to substitute this in z
the eqn like N=9+X+y-9=X+Y
then alok choose next value and substitute this at the end
N=9+9=18.

ans is 20
remember the rule
for X+Y-Z = 11 so 9+X+Y-Z=9+11= 20
for X*Y-Z = 18
for X-Y-Z = 2

Is this solution Helpfull? Yes (5) | No   

ravikumar  (13 years ago)

alok gives all three 9s
so, bhanu substitutes in X,Y,Z places
hence 9+9+9-9 = 18

0 because only equilateral triangle will have equidistant to its centre.

alok wants to maximiz so he will select 9,8,0. those digits.
whenvr bhanu minimizs .in dat case during substitute he puts z=9 & x or y=8 or0..so the ans will cme 8+0-9=-1
