Differential leveling between BMs A, B, C, D, and A gives elevation differences (in meters) of 6.352,

Question:

Differential leveling between BMs A, B, C, D, and A gives elevation differences (in meters) of 6.352, 12.845, 9.241, and 15.717, and distances in km of 0.6, 1.0, 1.3, and 0.5, respectively if the elevation of A is 886.891, compute the adjusted elevations of BMs B, C, and D, and the order of leveling.
