(c) A Dumpy Level was place at the mid point C of A and B which were 200 ft apart. The staff readings at A and B are 2.5 ft. and 4.6 ft. The instrument was then shifted and placed midway between A and C. The reading at A and B were 3.2 ft and 5.6 ft respectively. (1) Is the line of collimation adjusted? (ii) If not is it inclined upward/downward? (iii) What should be the staff reading at A and B when the level is adjusted?
