If x is the interest on y and y is the interest on z, the rate and time is the same on both the cases. What is the relation between x, y and z?  Select:
A) Y2 = xz	B) Y2 = xy	C) Y2 = Yz	D) Y3 = xz	E) Y5 = xY
X = (Y*NR)/100 Y = (Z*NR)/100   X/Y = NR/100 Y/Z = NR/100   X/Y = Y/Z   Y2 = XZ.Y2 = xznswer:Y2 = xz
