The answer is neither. If they are parallel they must have the same slope and if they are perpendicular the slopes cannot have the same sign. The slopes of the lines are both negative and unequal.
find the slopes of both lines.
5x+2y =3
y = (3-5x)/2 = -5x/2 +3/2
slope 1 = -5/2
2x+5y =8
y= (8-2x)/5 = -2x/5 + 8/5
slope 2 = -2/5

We know when equation of line is of form y = mx +c
then slope of line is m
Now, first line : 5x + 2y = 3 => 2y = -5x + 3 =>y = (-5/2)x + 3/2
and Second line: 2x + 5y = 8 => 5y = -2x + 8 => y = (-2/5)x + 8/5
Since neither m1 = m2 (for lines to be parallel) nor m1.m2 = -1 (for lines to be perpendicular). Thus lines are neither parallel nor perpendicular.
