The part (a) of the question was on trigonometry and required the use of tables. Rearranging the equation results in cos x = 0.8889 and from the Mathematical Tables, it showed x = 27.27o.
Most of the candidates scored above average in the question.

In part (b), Candidates were able to solve the expression but were unable to get the three greatest integers required. On solving the inequality,     7x – 2x < -13 gave x < -23/5. The three greatest integers were -3, -4    and -5.
