The following readings were obtained during differential levelling.
The reduced Level (RL) of point A is 240.000 m. The foresight and back sight between points A and TPI is 1.420 m and 2.024 m, respectively. Fore sight and back sight between points TP1 and TP2 is 2.100 m and 1.986 m, respectively. The back sight from B is 1.722 m. These are marked on the given figure. What is the RL at turning point-2 (TP2)? All values are in meters.
