4. In the two-peg test of a dumpy level, the following observations are taken: with level setup at M (midway between A and B), the rod readings on A and B are 1.155 m and 1.770 m, respectively. With level at P, the rod reading on A is 2.423 m and that on B is 2.999 m. If point P is located 1.67 m from A along the extension of line AB and 76.910 m from B, what should be the correct rod reading on the far rod for a horizontal line of sight (with the level still setup at P).
