The following consecutive staff readings were taken with a level and 3m leveling staff on a continuously slopping ground at a common interval of 20m:0.605, 1.235, 1.860, 2.575, 0.240,0.915, 1.935, 2.875, 1.825, 2.725. The R.L of the first point was 192.120. Rule a page of a level field book and enter the above readings. Calculate the reduced levels of the points and also the gradient of the line joining the first and last points.
