12.Postage on a parcel is calculated as £4.60, correct to the nearest 20p. Which of these could not be the actual cost of the postage?
(a)£4.55
(b)£4.50
(c)£4.65
(d)£4.80
13.Robert is converting 0.999... (with the 9s recurring forever) into a fraction. He lets x = 0.999... . Multiplying by 10 gives 10x = 9.999... . Subtracting x from 10x gives 9x = 9, so x = 1. Which statement correctly explains this result?
(a)Only approximately 1, since it never truly reaches 1.
(b)Only works because the recurring digit is 9.
(c)Exactly 1: the subtraction has no rounding at any step.
(d)Wrong: 10x minus x gives 9x = 8.999..., not 9.
14.A 3-character PIN starts with one letter chosen from A, B, C, D and E, followed by two different digits chosen from 1 to 9 (no digit may be used twice in the same PIN). Work out how many different PINs are possible.
(a)180
(b)22
(c)360
(d)405
15.Work out 3³ + 2⁴.
