The following consecutive readings were taken with a dumpy level:0.695...
Given readings: 0.695, 1.525, 2.395, 0.635, 0.605, 0.805, 0.125

Explanation:

A dumpy level is an optical instrument used in surveying and building to determine the relative heights or elevations of points.

1. Foresight (F.S.): It is the reading taken on a staff held on a point whose elevation is to be determined.

2. Backsight (B.S.): It is the reading taken on a staff held on a point of known elevation.

3. Intermediate Sight (I.S.): It is the reading taken on a staff held on a point between F.S. and B.S.

In the given readings, the instrument was shifted after the third and fifth readings. The readings 2.395 and 0.635 respectively represent F.S. and B.S.

Therefore, the correct answer is option 'A', which includes F.S. and B.S.

The following consecutive readings were taken with a dumpy level:0.695...
The first reading after changing the position of dumpy level is B.S. although this point should be exactly the same point where the last reading was taken with the previous position of dumpy level. it can be also noted that this B.S is found out to know the H.I so that the R.L for the next points are known. similar approach can be used for the rise and fall method as well. the last reading taken by an instrument at certain position is called F.S
