Two Pegs A and B were fixed on opposite banks of a $50$ m wide river. The level was set up at A and the staff readings on Pegs A and B were observed as $1.350$ m and $1.550$ m, respectively. Thereafter the instrument was shifted and set up at B. The staff reading on Pegs B and ... m and $0.550$ m, respectively. If the R.L. of Peg A is $100.200$ m, the R.L. (in m) of Peg B is _______.

In a survey work, three independent angles $X, Y$ and $Z$ were observed with weights $W_X, W_Y, W_Z$,respectively. The weight of the sum of angles $X, Y$ and $Z$ is given by: $1/ \big( \dfrac{1}{W_X} + \dfrac{1}{W_Y} + \dfrac{1}{W_Z} \big) \\$ $\big( \dfrac{1}{W_X} + \dfrac{1}{W_Y} + \dfrac{1}{W_Z} \big) \\$ $W_X +W_Y+W_Z \\$ $W_X^2 +W_Y^2+W_Z^2$
