(a) If 2x+y = 16 and 4x+y = 1/32, find the values of x and y.
(b) P, Q and R are related in such a way that P cc Q2 /R
When P = 36, Q = 3 and R = 4. Calculate Q when P = 200 and R = 2.
(a)This question involved the application of indices and simultaneous equation. A good number ofthe candidates were able to obtain the 2 simultaneous equations and solve them correctly.
(b) This was a question on variation. It involved finding the constant of variation and using the change of subject to find the unknown. It was fairly well handled by majority of the candidates.
