Question 1(a) was reportedly popular among the candidates and many candidates performed well.  However, quite a number of them displayed poor knowledge of ratio by substituting the values 2 and 3 for x and y respectively.  They were expected to recognise that if x:y = 2:3 then x/y = 2/3 or  x = 2y/3.   Similarly, they can be expressed as x = 2k and y = 3k where k is a constant.

Question 1 (b) was also well attempted.  However, it was noticed that many candidates could not draw the diagram.  Others did not add the man’s height to the calculated height and hence lost some marks.
