318868 The contribution of particle at the edge centre of a particular unit cell is

318869 A solid has a structure in which \(X\) atoms are located at cubic corners of unit cell, \(\mathrm{O}\) atoms are at the edge centres and \(\mathrm{Y}\) atoms are at cube centre. Then the formula of compound is \(X_{a} Y_{b} O_{c}\). If two atoms of \(\mathrm{O}\) are missing from any of two edge centres per unit cell, then the molecular formula is \(X_{p} Y_{q} O_{r}\). Then, find the value of \((\mathrm{p}+\mathrm{q}+\mathrm{r})-(\mathrm{a}+\mathrm{b}+\mathrm{c})\).
