Equilibrium · Solubility product of sparingly soluble salt

MX3AX2\ce{M3A2} is a sparingly soluble salt of molar mass yy g mol−1^{-1} and solubility xx g L−1^{-1}. The ratio of the molar concentration of the anion (AX3−\ce{A^{3-}}) to the solubility product of the salt is
  1. (1)154⋅y4x4\dfrac{1}{54}\cdot\dfrac{y^4}{x^4}
  2. (2)y5108x4\dfrac{y^5}{108x^4}
  3. (3)108⋅x5y5108\cdot\dfrac{x^5}{y^5}
  4. (4)1108 y4x4\dfrac{1}{108}\,\dfrac{y^4}{x^4}
