The elevation of point Z is 3,000 meters.
It can easily be seen what the elevation of point Z is, by just tracking the contour line on which it is marked. That is a basic contour line, thicker than the other lines, so its easier to track, and that specific contour line is marked with a height of 3,000 meters. Also, since we have the elevation above of 3,250 meters on a basic contour line, we can easily estimate the elevation of the contour line bellow on which the Z point is, because there's 4 contours in between them, and every next basic contour line comes as fifth, so every line is 50 meters lower or higher (depending where we go on the map), and
3,250 - (5 x 50) =
3,250 - 250 = 3,000
so we get the result of 3,000 meters of elevation.
