Three points, A, B and C 500 m apart on a straight road have 500 m, 505 m and 510 m as their reduced levels. The road is said to have
no gradient between A and C
a positive gradient between A and C
a negative gradient between A and C
a negative gradient between A and B
a positive gradient between A and B followed by a negative gradient between B to C.

There are giving RL's not Staf reading.

So +grade in forward side.

Please note the RL of the road is given not staff readings.

So, the right answer is B.

@Chulbul.

When staff reading decrease the land or road has Rising Gradient.
When staff reading increase the land or road has Falling Gradient.
So in this question there is a Rising gradient so option B is correct.

Chulbul is right. Answer should be C.
Chulbul said:   8 years ago
I think the answer should be (C).

A to C, the RL is increasing. If we consider a fix line of collimation, then the staff should descend so as to increase the staff reading.
The staff reading increases, if the level of ground descends.
I believe It's negative gradient.

Please clarify it.
