The temporary adjustments of a theodolite at each station are:
सही उत्तर: ख) Centring, levelling and focusing (removal of parallax)
Temporary adjustments are setting up/centring, levelling the plates and focusing; the others are permanent adjustments.

When the vertical circle of a theodolite is on the left of the observer while sighting, the observation is called:
सही उत्तर: क) Face left
Face left (telescope normal) means the vertical circle is to the observer's left.

In a properly adjusted theodolite, the horizontal axis must be:
सही उत्तर: ख) Perpendicular to the vertical axis
Permanent adjustments ensure the trunnion axis is perpendicular to the vertical axis, and the line of collimation perpendicular to the trunnion axis.

-
The fundamental axes of a theodolite include the vertical axis, the horizontal (trunnion) axis and the:
सही उत्तर: घ) Line of collimation
The fundamental lines of a theodolite are the vertical axis, horizontal axis, line of collimation and axis of the plate level.

Contour lines cross ridge lines and valley lines at:
सही उत्तर: ग) Right angles
Contours are perpendicular to the direction of steepest slope, so they cross ridge and valley lines at right angles.

The bearing of line AB is 60° and the included angle ABC measured clockwise from BA to BC at B is 100°. What is the bearing of BC?
सही उत्तर: क) 340°
Back bearing of AB = 240°; bearing of BC = 240° + 100° = 340°.

The included angle between two lines AB and AC at A is to be found from bearings of AB = 30° and AC = 110°. The angle BAC is:
सही उत्तर: ग) 80°
Included angle = 110° − 30° = 80°.

Which of the following is a likely source of local attraction in compass surveying?
सही उत्तर: घ) Steel structures, iron pipes or electric cables nearby
Magnetic materials and currents (iron, steel, cables) near a station deflect the needle, causing local attraction.

-
Which of the following is a common use of contour maps?
सही उत्तर: क) Estimating the capacity of a reservoir
Contour maps help in reservoir capacity, catchment area, route location and intervisibility studies.

The true bearing of a line is 210° and magnetic declination is 4° West. The magnetic bearing is:
सही उत्तर: घ) 214°
True = Magnetic − West declination, so Magnetic = 210° + 4° = 214°.
