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