A tacheometer was set up at station P and observations were taken on a vertically held staff at Q with the vertical circle reading zero. The three stadia hair readings are 1.9 m, 1.6 m, and 1.3 m. The staff reading on a Bench Mark of elevation +100.0 m from the same setup with a vertical circle reading of zero is 2.5 m. Assuming the multiplying constant as 100 and the additive constant as 0, the horizontal distance PQ and the elevation of point Q are respectively:
