4 (b) The following consecutive readings were taken with a level and a 4.0m staff on a continuously sloping ground at common interval of 30m. 0.780, 1.535, 1.955, 2.430, 2.985, 3.480, 1.155, 1.960, 2.365, 3.640, 0.935, 1.045, 1.630 and 2.545. The reduced level of the first point 'A' was 180.750 m. Rule out a page of a level field book and enter the above readings. Calculate the reduced levels of all the points and apply proper check for calculation.
