Question 1

Which of the following statements are correct?
1) For a closed traverse the sum of the northings is equal to the sum of southings.
2) The sum of interior included angles is equal to (n – 2)×180 ° for a closed traverse.
3) Latitude of a line is its projection onto the reference meridian.
4) When angular measurements are more precise than the linear measurements the traverse is balanced by bowditch rule.

Question 2

The magnetic bearing of a line is 48⁰24^’. Calculate the true bearing if the magnetic declination is 5⁰38’east.

Question 3

In a closed traverse PQR, the following readings were taken

If station P is free from local attraction, then correct bearing of RQ is

Question 4

The local means time at a place located in longitude 90 ° 40' E when the standard time is 6 hours and 30 minutes and the standard meridian is 82 ° 30' E is

Question 5

In chaining an area containing a pond, two points C and D were selected on either sides of chain station A such that C, A and D points lie on a line. The point B is on the chain line AB. If distance AC, BC, AD and BD are 35 m, 100m, 45 m and 95 m respectively, then the length (in m) of chain line AB is

Question 6

In a badly maintained field book, following observations were found
Bearing of line AB with true north = 123 °
Acute angle ABC = 82 °
When extended line BC is rotated by an angle of 30 ° (clockwise), it meets the line CD.
If the bearing of line DC with true North is more than 180 °, then its bearing value (in degrees) is
