We can know, the distance between the floor and slab is always near around 3 m so answer we can predict options which are near about 3 m and second the technical specifications in the questions staff is held inverted so the b.s- f.s= 1.505-(-1.795 ) (- because staff is inverted) and answer is 3.3 m.

HI = RL + Staff reading on floor.
= 99.995 + 1.505 = 101.5m.
Here the staff was inverted against the roof and the staff reading is 1.795m.
So, HI + inverted staff reading.
= 101.5 + 1.795 = 103.295m.
So floor level = 103.295 - 99.995 = 3.3m.
= 99.995 + 1.505 = 101.5m.
Here the staff was inverted against the roof and the staff reading is 1.795m.
So, HI + inverted staff reading.
= 101.5 + 1.795 = 103.295m.
So floor level = 103.295 - 99.995 = 3.3m.

Agri @Sam, The answer should be 103.295 M this is the RL of roof slab but if the distance is wanted between the roof level and the floor level it should be 3.295 m.

H.I = R.L+B.S.
= 99.995+1.505.
= 101.5.
The Floor Level Below The Slab = H.I+Inverted Staff Reading.
= 101.5+1.795.
= 3.30m.
= 99.995+1.505.
= 101.5.
The Floor Level Below The Slab = H.I+Inverted Staff Reading.
= 101.5+1.795.
= 3.30m.

If the benchmark of a station 'A' is 100, Back sight is 1.4m, foresight is 1.5m then what will be the level of the line of sight?
Can anyone answer this?

H.I of Instrument = 99.995+1.505 = 101.5 m.
As the second staff reading is negative this,
= 99.995-1.795= 98.2m.
= 101.5 - 98.2 = 3.3m answer.
As the second staff reading is negative this,
= 99.995-1.795= 98.2m.
= 101.5 - 98.2 = 3.3m answer.

Reduce level of bench mark 94.55m.
Staff readings of floor and roof 1.53 , -2.5.
Find the reduce level of both points?

@Muskaan.
The height of the instrument = 100 + 1.4
RL of line of sight = 100+1.4-1.5 = 99.99.
The height of the instrument = 100 + 1.4
RL of line of sight = 100+1.4-1.5 = 99.99.

Simple the staff reading on the floor plus inverted staff reading.
1.505 + 1.795 = 3.30m.
1.505 + 1.795 = 3.30m.

The staff reading on the floor + inverted staff reading.
1.505+1.795 = 3.300.
1.505+1.795 = 3.300.
