A chaining pass a porid,stations P and Q were selected on opposite side of the pond. A line PA,200 m long, was set out of the left of PQ ,and a line PB was set out on the right such that A,Q and B are collinear. The length of PB was 250m. The length of AQ and QB were meassured to be 125m and 150m respectively. The chainage at P is 1020.55m. Calculate the chainage of Q.

The following staff reading were observed with a level & a 4 m staff on a continuously sloping ground at a common nterval of 15m. The reading are 0.880,1.632,2.530,3.085,3.580,1.255,2.060,2.465,3.740,1.035,1.145,1.1730 and 2.645. The reduced level of the first point was 780.150. Rule out a page of level-book and enter the above reading. Calculate the reduced levels and the gradient of the line joining the first & last points.
