In quadrantal bearing system, back bearing of a line may be obtained from its forward bearing, by
adding 180°, if the given bearing is less than 180°
subtracting 180°, if the given bearing, is more than 180°
changing the cardinal points, i.e. substituting N for S and E for W and vice-versa
none of these.

Qudratical bearing system is also known as reduced bearing system.

Yes correct @Nilesh.

I agree with you @Urmi.

Correct @Nilesh.

Yes, right @Nilesh.

In this question, bearing is taken at QB system. Between fore and back bearing the difference is 180'. In QB system certain if we add (when the angle is <90) or subtract 180(when the angle is >90) from a certain angle then the resultant angle can find out by changing N to S and E to W.

The value of a quadrantal bearing lies between 0' to 90'.

Quadrantal bearings are obtained by the surveyor's compass.

You are right @Nilesh.
