Like the Intermediate Challenge earlier this year, the Junior challenge poses a wide range of questions, designed to test mathematical thinking, rather than simply remembering facts or techniques.
Whilst the challenge is an opportunity for students to shine individually (and we will let you know results as soon as they are in), this is also a House competition, and will contribute towards house points at the end of the year.
All questions are multiple choice, but for the harder questions guessing is very much discouraged by the unusual method of marks being taken away for wrong answers! It is also entirely non-calculator, and although paper working is allowed (essential), apart from a pencil and rubber no other equipment is allowed.
Headline results will of course be published here and in the newsletter, but until they are here are a few questions from this year's paper to think about...
3. Which of the following has exactly one factor other than 1 and itself?
A 6 B 8 C 13 D 19 E 25
7. A small ink cartridge has enough ink to print 600 pages. Three small cartridges can print as many as two medium cartridges. Three medium cartridges can print as many pages as two large cartridges. How many pages can be printed using a large cartridge?
A 1200 B 1350 C 1800 D 2400 E 5400
A 132 B 145 C 161 D 178 E 193
20. Aroon says that he is 50 years, 50 months, 50 weeks and 50 days old. What age will he be on his next birthday?
A 56 B 55 C 54 D 53 E 52
25. The interior angles of a triangle are (5x+3y), (3x+20) and (10y+30), where x and y are positive integers.
What is the value of x+y?
A 15 B 14 C 13 D 12 E 11
If you want to have a go at these, feel free to submit your answers on the form below, and we'll let you know in due course how you've scored!
Good luck!
