Elevation of top Q of a hill, a staff of 2 m height was erected and observations were made from stations P and R, 60 m apart. The horizontal angle measured at P between R and the top of the flag staff was 60°30' and that measured at R between the top of the flag staff and P was 68°18'. The angle ofelevation to the top of the flag staff from P = 10°12' and from R = 10°48'. Staff readings on BM when instrument was at P = 1.965 m and that with instrument at R = 2.055 m. Calculate the elevation of the top of the hill if reduced level of BM=100m?

A is a point having an elevation of 130.48 m above datum, and B and C are points of unknown elevation. B is in between A and C. By means of an instrument set 1.22 m above B vertical angles are observed that to A being -14°45' and that to C being +8.32. The horizontal distance AB is 547.20 and the horizontal distance BC is 923.25 m. Making due allowance for earth's curvature and atmospheric refraction. Compute the elevation (meters) of C.
