Question

In a closed loop traverse of 1 km total length, the closing errors in departure and latitude are 0.3 m and 0.4 m respectively. The relative precision of this traverse will be

• A. 1:2000
• B. 1:3000
• C. 1:4000
• D. 1:5000

Answer 1

The correct option is A 1:2000

$RelativePrecision=\frac{1}{p/e}$

where, p = Perimeter of traverse

e = Closing error

$e=\sqrt{{0.3}^2+{0.4}^2}=0.5$

$Relativeprecision=\frac{1}{\frac{1000}{0.5}}=\frac{1}{2000}$
