927. In a two-peg test, with the level midway between A and B the readings are A = 1.500 m, B = 1.000 m. With the level close to A the readings are A = 1.400 m, B = 0.960 m. The line of collimation is:

     कInclined downwards, giving an error of 0.060 m at B खCorrectly adjusted गInclined upwards, giving an error of 0.040 m at B घInclined upwards, giving an error of 0.060 m at B

928. From a benchmark of RL 100.000 m, a back sight of 1.200 m is taken; then a fore sight of 2.500 m on a change point, after which the level is shifted and a back sight of 1.800 m is taken on the same change point. The height of instrument at the second set-up is:

     क100.500 m ख101.200 m ग98.700 m घ102.300 m
