A level circuit is run a total distance of 10 km from BM 30 to set three other benchmarks in the vicinity of a construction project (see figure below). The level loop consists of four instrument set- ups. The first set-up is between BM 30 and BM 30A, the second set-up is between BM 30A and BM 30B, the third set-up is between BM 30B and BM 30C, and the fourth set-up is between BM 30C and BM 30. The known elevation of BM 30 is 456.78 m. When closing the level loop, its elevation is observed to be 456.71 m. BM 30 Elev 456.78 3.15 km 4.15 km BM 30A Observed Elev 567.89 BM 300 Observed Elex 543.21 1.76 km 950m BM 308 Observed Elev. 576.43 What is the adjusted reduced level of BM 30B in meters, assuming that the elevation error at each point along the line of levels is directly proportional to the cumulative number of set-ups up to that point?
