Sets and Relations question bank (Maths)

Let $\mathrm{A}=\{-3,-2,-1,0,1,2,3\}$ and R be a relation on $A$ defined by $x R y$ if and only if $2 x-y \in\{0,1\}$. Let $l$ be the number of elements in R. Let $m$ and $n$ be the minimum number of elements required to be added in R to make it reflexive and symmetric relations, respectively. Then $l+\mathrm{m} \mathrm{n}$ is equal to :-
