For integers x and y, if 91x = 8y, which of the following must be true?
I. y > x
II. y/7 is an integer
III. The cube root of x is not necessarily an integer	Choose the correct choice.
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   NOT TRUE   Statement 2: y/7 is 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/7 must be an integer   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.   TRUII and III   Answer:-II and III
