Concept:The bearing of a point is measured clockwise from north. The reverse bearing differs by 180∘.Solution:Bearing of Q from P is 120∘.This means Q is located 120∘ clockwise from north when measured at P.We have to find the bearing of P from Q.The direction from Q back to P is exactly opposite to the direction from P to Q.To get the opposite direction, add 180∘ to the given bearing.So, bearing of P from Q=120∘+180∘.This gives 300∘.Since 300∘ is within the valid range 0∘ to 360∘, no further correction is needed.Answer:Option C (300∘)
