1 (a) Following staff readings were taken on an uneven ground with a 4 m leveling staff. Calculate reduced levels of the points by height of instrument method and apply usual checks. The instrument was shifted after 3rd, 6th and 9th readings. The first reading was taken on a bench mark of 100 m. 1.20, 2.65, 3.50, 2.40, 1.95, 0.90, 1.80, 3.70, 2.50, 0.85, 1.70.
