If a 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 a, y and z?  Options
A) Y^2 = aZ	B) Y^3 = aZ	C) Y^3 = aY	D) Y^1 = aZ	E) Z^3 = aZ
a = (Y*NR)/100 Y = (Z*NR)/100   a/Y = NR/100 Y/Z = NR/100   a/Y = Y/Z   Y^2 = aZ   ANSWER:Y^3 = aZ
