This question was reported to be quite unpopular with the candidates and the performance of those who attempted it was described as fair. Only few of them were reportedly able to obtain the vector q. Candidates were expected to find the unit vector in the direction of (n + 5) as follows: (n + 5s) =  + 5 = . |n + 5s| =  = 7. Unit vector =  = . Hence, the required vector q = 35 = .
