In carrying out the permanent adjustments of a level by, the following observations were made: Instrument at peg (C) midway between points A and B, 100m apart. Readings at points A and B are 2.500m and 3.500m, respectively. Instrument at peg (D) in line of AB such that AD-120m and BD-20m, Readings at points A and B are 1.500m and 2.600m, respectively. Check whether the instrument needs permanent adjustment or not and whether the line of sight is inclined upward or downward. What should be the correct reading at (A and B) if the instrument is to be adjusted?
