Sets, Relations and Functions: JEE Main 2026 Mathematics question

Let $A=\{-2,-1,0,1,2,3,4\}$. Let R be a relation on A defined by $xRy$ if and only if $2x+y\le2$. 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 $l+m+n$ is equal to :
