Q#1. The staff readings 9.01, 6.62, 5.15, 2.12, 0.98, 10.68, 12.45, 9.75 were observed with a dumpy level. The level was shifted after the second, fourth, and sixth readings. The first reading was taken on a bench mark of R.L. of 355.50 ft. Calculate the reduced level of change points, and the difference of level between the first and last point by the height of plane of collimation method. Apply the usual checks. (c)
