For integers x and y, if 91x = 8y, which of the following must be true?
I. x > y
II. y is not an integer
III. The cube root of x is an integer
Choose the correct choice from the following answers.
A) I only B) II only C) III only D) I and II E) II and III
Statement 1: y&gt;x   When y=x=0, equation holds but y is not greater than x   When x=-8 and y=-91, equation again holds but x&gt;y   TRUE   Statement 2: y is not an integer   Since x and y are integers, 91x and 8y must also be integers.   It is given that 91x=8y   or 13*7*x = 8 y   or 13x = 8y/7   To balance the equation, y must be an integer   NOT TRUE   Statement 3: The cube root of x is an integer   x can be equal to 2*2*2*3 and for this value of x,y will be 13*7*3   So, x may or may not be a cube root.   NOT TRUE   I onlynswer:-I only
