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