MARK SCHEME

7280.01

GCSE MATHEMATICS Introduction The mark scheme normally provides the most popular solution to each question. Other solutions given by candidates are evaluated and credit given as appropriate; these alternative methods are not usually illustrated in the published mark scheme. The solution to a question gains marks for correct method and marks for accurate working based on this method. The marks awarded for each question are shown in the right hand column and they are prefixed by the letters M, A and MA as appropriate. The key to the mark scheme is
1052 4 x = 10.6 13 (a) 70 and 20 (b) Two bars drawn to correct heights (6.8 and 9.6) (c) 7.5 + 52.5 60 (d) x # 20 or 144 = 3.6, 3.6 # 20 = 72 60 40 x h = x # 20 = x 3 60 3

Chapter I: Permutations, combinations, occupancy problems. We start with some basic counting principles and examples. I.1. Two ways of counting the same ﬁnite set give the same answer. Example I.2. (Hand shaking lemma). The number of delegates at a conference who shake hands an odd number of times is even. Proof. Let D1 , ..., Dn be the delegates, and let X = {(i, j) : Di and Dj shake hands}, and let k = |X|. We count k in two ways. First k is even because it is twice the number of handshakes. Secondly k = k1 + ... + kn where ki = the number of times that Di shakes hands. THUS k1 + .. + kn is even, which implies that evenly many of the ki are odd, which is what we wanted to prove. I.3.…

When coming up with a solution to the problem I checked with the leadership to make sure it was okay to implement my plan. Leadership told me not to over think the problem at hand, just come up with a quick fix to the problem considering we were only here for six months. Producing many ideas helped me have a choice of what I wanted to do. For an individual to come up with more than one idea gives an individual a broader choice, which makes solving a problem a whole lot easier. Being a leader is not hard to do; it’s about coming up with ideas, implementing them and leading from the front with integrity.…

This mark scheme is published as an aid to teachers and candidates, to indicate the requirements of the examination. It shows the basis on which Examiners were instructed to award marks. It does not indicate the details of the discussions that took place at an Examiners’ meeting before marking began, which would have considered the acceptability of alternative answers. Mark schemes should be read in conjunction with the question paper and the Principal Examiner Report for Teachers.…
