A road in a hilly terrain is to be laid at a gradient of $4.5\%$. A horizontal curve of radius $100\:m$ is laid at a location on this road. Gradient needs to be eased due to combination of curved horizontal and vertical profiles of the road. As per IRC, the compensated gradient (in $\%$, round off to one decimal place), is _______.

A theodolite is set up at station $A$. The $RL$ of instrument axis is $212.250\: m$. The angle of elevation to the top of a $4\: m$ long staff, held vertical at station $B$, is $7^{\circ}$.The horizontal distance between stations $A$ and $B$ ... the errors due to curvature of earth and refraction, the $RL$ (in $m,$ round off to three decimal places) of station $B$ is ________.

A theodolite is set up at station A and a $3$ m long staff is held vertically at station B. The depression angle reading at $2.5$ m marking on the staff is $6^{\circ}10’$. The horizontal distance between A and B is $2200$ m. Height of instrument at station A is $1.1$ m and R.L. of A is $880.88$ m. Apply the curvature and refraction correction, and determine the RL of B (in m) _______

The following data are related to a horizontal curved portion of a twolane highway: length of curve $200$ m, radius of curve $=300$ m and with of pavement $=7.5$ m. In order to provide a stopping sight distance (SSD) of $80$ m, the set back distance (in m) required from the centre line of the inner lane of the pavement is $2.54$ $4.55$ $7.10$ $7.96$
