Answers and working

Questions 1 to 15

  1. 1.A (12). The total is 3 × 734 = 2202. The visible parts make 2190, so the hidden digits are worth 12. Whatever way they fit, the digits add to 12.
  2. 2.B (8:58 pm). The smallest number that both 4 and 14 divide into is 28. So they meet again 28 minutes after 8:30 pm, which is 8:58 pm.
  3. 3.D (Pia). From heaviest to lightest, the order is Pia, Hana, Milo, Carlos, Theo. So the answer is Pia.
  4. 4.C (37). The primes 29, 31, 37 come one after another and add up to 97. The largest is 37.
  5. 5.C (50°). 180° − 55° − 75° = 50°.
  6. 6.C (4). Take 2x from both sides: 2x − 15 = -7. Add 15: 2x = 8. Divide by 2: x = 4.
  7. 7.C (21). The magic total is 3 × centre = 57. The diagonal through * gives 57 − 19 − 17 = 21.
  8. 8.D (4). Listing the rectangles with the smaller side first, 4 of them have an area of 30.
  9. 9.B (14). Take the sizes one at a time: a square of side k can sit in (3 − k + 1) × (3 − k + 1) positions. Adding those up from k = 1 to 3 gives 14, which on a square grid is just 1² + 2² + … + 3².
  10. 10.D (10 members). 6 + 23 − 4 = 25 do at least one, and the other 10 of the 35 do neither. So the answer is 10 members.
  11. 11.C (Fay). Try each child as the one with the ball and count the true statements. Only when Fay has it is exactly one statement true.
  12. 12.C (33 × 7 ÷ 3). 33 ÷ 3 × 7 = 77, and so does 33 × 7 ÷ 3.
  13. 13.E (1/12). Of the silver ones, 10 to 12, the ones whose number is a factor of 40: 10. That is 1 of the 12: 1/12.
  14. 14.A (7/8). The big square has 16 small squares. The shaded part is 14 squares. So 14 out of 16 is shaded: 7/8.
  15. 15.C (14). Call the smaller number n. The larger is 7n, so the two multiply to 7 × n × n = 1372. That makes n × n = 1372 ÷ 7 = 196, so n = 14 and the larger number is 98.

Questions 16 to 25

  1. 16.E (2/5). 6 of the 15 rolls were a number greater than 4, and 6/15 in simplest form is 2/5. So the answer is 2/5.
  2. 17.E (18). Listing every shape, with turned and flipped copies counted as the rules say, gives 18 shapes.
  3. 18.B ((140 ÷ 7) + (56 ÷ 7)). 196 = 140 + 56, so 196 ÷ 7 = (140 ÷ 7) + (56 ÷ 7), which is 28.
  4. 19.E (1). Only the folds that make both halves match count, so this shape has 1 line of symmetry.
  5. 20.D (Carlos). Try each child as the one with the ball and count the true statements. Only when Carlos has it is exactly one statement true.
  6. 21.D (5). The largest odd number from those digits is 95403. Its thousands digit is 5.
  7. 22.D (109). The primes 101, 103, 107, 109 come one after another and add up to 420. The largest is 109.
  8. 23.B (13). Only 6, 10 and 13 multiply to 780 and add to 29. The largest is 13: 13.
  9. 24.C (5). 25 = 5 × 5, 30 = 2 × 3 × 5. The primes they all share multiply to 5.
  10. 25.C (54°). The angle at D equals the angle at A (alternate angles), 48°, so x = 180° − 48° − 78° = 54°.

Questions parents ask

Is this paper right for Year 7?
Yes. The junior challenge is set for Year 8 and below, and most Year 7 children who sit it find the last ten questions hard. That is how it is meant to be.
How is it marked?
Questions 1 to 15 are worth 5 marks each and 16 to 25 are worth 6, so the paper is out of 135. Nothing is taken off for a wrong answer, so it is worth answering every question.
Can my child use a calculator?
No. The challenge allows no calculator or measuring instruments, only rough paper. Practise the same way.
Are these real past papers?
No. We write our own questions in the challenge's published shape. Past papers belong to the UK Mathematics Trust, and we are not connected with it.
