An element E form amphoteric oxide ${\mathrm{E}}_{\mathbf{x}}{\mathrm{O}}_{\mathbf{y}}$. If ${\mathrm{E}}^{+\mathrm{y}}$ contain same number of 3 d electrons as present in cation of amphoteric oxide of Manganese.

(a) If the maximum possible number of electrons present in orbitals having zero nodal planes in the cation of E in the amphoteric oxide is 'P'.

(b) Atomic number of element E is 'Q'.

Calculate the value of $\left(\frac{P+Q}{x+y}\right)$.
