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?  Choose the most appropriate option:  A) Y2=XY  B) X2=YZ  C) Y2=XZ  D) Z2=XZ  E) Y2=XZ
X = (Y*NR)/100 Y = (Z*NR)/100   X/Y = NR/100 Y/Z = NR/100   X/Y = Y/Z   Y2 = XZ   Answer:Y2=XZ
