Sets And Relations

Let \(\mathrm{A}=\{1,2,3,4,5\}\). Let \(\mathrm{R}\) be a relation on \(\mathrm{A}\) defined by \(x \mathrm{R} y\) if and only if \(4 x \leq 5 \mathrm{y}\). Let \(\mathrm{m}\) be the number of elements in \(\mathrm{R}\) and \(\mathrm{n}\) be the minimum number of elements from \(\mathrm{A} \times \mathrm{A}\) that are required to be added to R to make it a symmetric relation. Then m + n is equal to :
