The UK JMC is about solving interesting problems, not about lucky guessing. You get more marks, and more satisfaction, by doing one question carefully than by guessing lots of answers. The questions on this paper challenge you to think, not to guess. If you mark the sheet in the wrong place, or leave bits of rubber stuck to the page, the machine will 'see' a mark and interpret this mark in its own way. The machine 'sees' all black pencil markings even if they are in the wrong places. Do not write or doodle on the sheet except to mark your chosen options. Your Answer Sheet will be read only by a dumb machine. Each incorrect answer to Questions 2-25 loses 2 marks. Six marks are awarded for each correct answer to Questions Each incorrect answer to Questions 6-20 loses mark. Five marks are awarded for each correct answer to Questions -5. When you have checked your answers to these, have a go at some of the later questions. Do not expect to finish the whole paper in hour. Mark at most one of the options A, B, C, D, E on the Answer Sheet for each question. Candidates in Northern Ireland must be in School Year 9 or below. Candidates in Scotland must be in S2 or below. Candidates in England and Wales must be in School Year 8 or below. The use of rough paper is allowed calculators and measuring instruments are forbidden. No answers, or personal details, may be entered after the allowed hour is over. Do not open the paper until the Invigilator tells you to do so. 1 Junior Mathematical Challenge Past Papers and SolutionsДў UKMT UKMT UKMT UK JUNIOR MATHEMATICAL CHALLENGE TUESDAY 26th APRIL 2005 Organised by the United Kingdom Mathematics Trust from the School of Mathematics, University of Leeds RULES AND GUIDELINES (to be read before starting).
