It depends where the scales are situated. If there are side-by-side below the man,s center of gravity, then each scale should read the same -- about 400 N, which is half of the man's body weight. If the scales are farther off the man's center of gravity (the man's legs are at an angle), then the scales would read less than 400 N.
