Many candidates attempted the (a) part of the question and the performance was fair. However, in expressing the logarithm, some candidates wrongly wrote
log x2 = log (2 – x) instead of log x2 = log (2-x)
log(1-x) 1-x
The part (b) of the question was poorly done. Their apparent difficulty was in reducing the word problem to simple equations. Candidates were expected to assign variables say x and y to represent the amount of money Ade and Chidi have respectively. The required equations are: x - 5 = y + 5 (or x – y = 10) and
x + 5 = 2(y – 5) i.e. 2y – x = 15. On solving simultaneously, x = N35 and
y = N25.
