if the height of the instrument is given, then no need to calculate RL OF NSTRUMENT axis right?

No... Still u have to calculate RL of instrument axis. RL we measured from BM.

RL is a vertical distance between a survey point and the datum surface.

Ma'am kab time par kaun sa formula use kaise karna hai please help 🙏

[@erashmam25]

First draw karo staff, tripod stand and angle given data se then formula uske according aa jayega.
When line of sight horizontal
D = (f/i)S + (f+d)
For line of sight inclined, staff vertical
D = (f/i) × S² cosθ + ( f+d)cosθ
1) for +ve angle
V = D tan θ
RL of staff = RL of instrument axis + V - h
2) for -ve angle
RL of staff station = RL of instrument axis - V - h
