A tacheometer is setup at station A and the staff is held vertical at a point B. The telescope inclined at an angle of depression 10° to the horizontal, the readings on the staff are 2.680, 1.825, 1.000m. If the height of instrument (H! ) is 1.40m and R.L. of station A is 360.8 m, then the R.L. of point B is cm. [Take multiplying and additive constant of the instrument to be 100 and 1 respectively]

A tacheometer was set up at station P and observations were made to two stations Q and R. The vertical angles to Q and R were 5°30’ and 1°08’ The cross-hair readings at Q were 2.105, 2.47 and 2.835 and those at R were 2.215, 2.56 and 2.905. The staff were held vertical in both cases. The instrument constants were 100 and 0.3. The reading from P to a BM of RL 285.35m was 2.255. The horizontal angle QPR measured was 58°30’. Find the distance QR, the gradient from Q to R and the RLs of Q and R.
