   If the RL of a BM is 100m, the back sight is 1.415m and the foresight is 1.670m, the RL of the forward station is

   1. 101.670m
   2. 101.415m
   3. 99.745m
   4. 98.585m
   Show answer

   Answer: (3) 99.745m

   Height of instrument = RL of BM + BS = 100 + 1.415 = 101.415 m. RL of forward station = HI − FS = 101.415 − 1.670 = 99.745 m.
