Reciprocal levelling is performed for points P and Q by placing the same levelling instrument at A and B. The observations of staff readings are tabulated as below.
Instrument location | Station P (m) | Station Q (m) |
|---|---|---|
A (near P) | 1.512 | 2.100 |
B (near Q) | 0.680 | 1.302 |
If the Reduced Level (RL) of P is 115.246 m, then the true RL of Q, in m, is ____ (rounded off to 3 decimal places)
