(b) The following consecutive readings were taken with a dumpy level along a chain line at a common interval of 15m. The first reading was at a chainage of 165m where the reduced level is 98.085. The instrument was shifted after the fourth and ninth readings. 3.150, 2.245, 1.125, 0.860, 3.125, 2.760, 1.835, 1.470, 1.965, 1.225, 2.390, and 3.035 m. Find the reduced level of all the points by rise and fall system.
