Question

If the quadrantal bearing of a line is N 38^o E, then the whole circle bearing of the line is - 
1. 48^o
2. 52^o
3. 322^o
4. 38^o

Answer 1

Correct Answer - Option 4 : 38^o

Concept:

Whole circle bearing of any line is its deviation measured in the clockwise direction from the north end reference.

Important table for conversion of a whole bearing reding to the quadrantal bearing is given below:

Sr No.	Whole Circle Bearing (WCB)	Quadrantal Bearing (QB)	Quadrant
1	0° to 90°	WCB	NE
2	90° to 180°	180° - WCB	SE
3	180° to 270°	WCB – 180°	SW
4	270° - 360°	360° - WCB	NW

 

Calculation:

Given bearing exist in the first quadrant (0° to 90°), so WCB equal to QB

WCB = 38°
