Question 1
Permissible limits of error in chaining for measurement on rough or hilly ground is ______.
Question 2
The distance between two points measured along a slope is 540 m. The horizontal distance between them, if the slope is 1 in 6, is _______ m.
Question 3
A surveyor measured the distance between two points on the plan drawn to a scale of 1 cm = 40m and the result was 468 m. later, however, he discovered that he used a scale of 1 cm = 20 m. true distance between the points will be-
Question 4

Question 6
If h is the difference in height between end points of a chain of length the required slope correction is ______.
Question 7
The cuvature and refraction effects are taken into account in the following case:
Level is set-up over A and the staff is held at B.
R.L. of A = 150.000 m
Height of instrument at A = 1.000 m
Reading of staff at B = 1.800 m
Distance AB = 500 m
The RL of B (in m) is
