Levelling Problem No 8 - Fly Levelling Missing Values Calculation ( Falling Ground )

In running fly levelling from a BM of RL 100 m, the following readings were taken Back Sights 3.125 1.030 1.295 1.855 Fore Sights 1.225 3.290 2.085 From the last position of the instrument, 6 pegs at 25 m intervals are to be set out on a uniformly falling gradient of 1 in 250. The top of first peg is to have a RL of 99.205 m. Work out the staff readings required to set out the tops on the given gradient. Show the results as it is shown in a level book.
