Q1:

If the angular measurements of a traverse are more precise than its linear measurements, balancing of the traverse, is done by

A Bowditch's rule

B Transit rule

C Empirical rule

D all of the above.

ANS:B - Transit rule

All three options are used for balancing the closed traverse and if angular measurements are more precise than linear measurements then the answer is transit rule. Bowditch rule = this rule is used to balance the traverse when angular and linear measurement are (equally) precise.
Transit rule = this rule is used when angular measurement is (more) precise than linear measurement. Balancing is done by two methods 1 transit and 2 Bowditch.
If angular measurement are precise then transit method is used.
If linear measurements are precise than angular then Bowditch method is used. In Bowditch method, both angular and linear are given equal precision.
In axis method, angular measurements are measured accurately and corrections applied to linear measurements only.
