2(a) The following staff readings were taken on a uneven ground with a 4 m leveling staff. Calculate reduced levels of all the points by Height of instrument method and apply usual checks. The instrument was shifted after 3 rd , 6th and 9 th readings. Thefirst reading was taken on a bench mark of 100 m
