Extracted text: Problem 1. While leveling between two points P and Q on opposite banks of a river, the level was first set up near point P and the staff readings observed at point P and Q were 1.385 m and 3.005 m respectively. After this level was set up near point Q and the observed readings on point P and Q were 0.750 m and 2.320 m respectively. If the reduced level of point P was 120.00 m, determine the reduced level of point Q.
