Leena cut small cubes of 3 cubic cm each. She joined it to make a cuboid of length 10 cm, width 3 cm and depth 3 cm. How many more cubes does she need to make a perfect cube? Alok and Bhanu play the following min-max game.Given the expression

N=26+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 and 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)-55
b)107
c)44
d)26
