In a levelling survey, the summation of all back sights and the summation of all foresights are 7.475 m and 7.395 m, respectively. The reduced level of the initial benchmark is 100.000 m. The reduced level of the last point where the staff is held will be

The permanent adjustment of theodolite is made in a specific sequence so as to avoid any disturbance in the previous adjustment caused due to next adjustment. The correct sequence is best represented by

Following bearings are observed while traversing with a compass.

Calculate the corrected fore bearing of the line BC.

Staff reading on the floor of a verandah of school building is 1.815 m and staff reading when held with bottom of staff touching the ceiling over the verandah is 2.870 m. R.L. of the floor is 74.500 m Height of the ceiling above floor is

The levelling staff held at a distance of 200 m is read at 4.54 m with the bubble out of centre by 2 divisions towards the observer. If the sensitiveness of the bubble is 25 secs/division, and 1 division = 2 mm, then actual staff reading must have been

Reciprocal levelling was carried with the help of a dumpy level and the following observations were recorded:

Consider the following observations for a closed traverse PQRS.

Which of the following option represents correct value of the missing data (variable)?

A page of a level book was defaced so that the legible figures are given in the table.

Where, BS = Back sight IS = Intermediate sight; FS = Fore sight RL = Reduced Level.

The value of foresight (FS), X₃ =
