Q. For the equation

\frac{a - x}{a} + \frac{2 a - x}{2 a} = \frac{3 a - x}{3 a}

, which of the following relation holds good?

{log}_{2 a} a = x

{log}_{3 a} 2 a = y

{log}_{4 a} 3 a = z

x y z - 2 y z

x = {log}_{2 a} a, y = {log}_{3 a} 2 a a n d z = {log}_{4 a} 3 a

x y z + 1 =

s i n^{2} A = x

then sin 3A. sin A is polynomial in x, whose degree is equal to

x = {log}_{2 a} a, y = {log}_{3 a} 2 a, z = {log}_{4 a} 3 a

1 + x y z = 2 y z
