When this triangle is placed inside a tightly fitting rectangle: you get another triangle with angles of 90 degrees (square since 90 degrees) and 64 degrees (since 64 is square number). The remaining angle is 24 degrees. Puzzle solution SP3 Sally is 73 and Becky is 37. Puzzle solution SP4 2 cuboids balance 3 cylinders So 1 cylinder = 2/3 cuboid So 1 cuboid = 1 cylinder + 2 cubes So 1 cuboid = 2/3(cuboid) + 2 cubes In diagram 1 cube + 1 sphere = 1 cuboid Therefore to balance a red sphere you need 5 cubes. Puzzle solution SP5 Let the number of posts behind her = n The total number of posts = n + 1 So, 3/4n + 1/3n = n + 1, So, 9n +4n = 12n + 12 So, 13n - 12n = 12, So, n = 12 The number of posts is n + 1 = 13 Puzzle solution SP6
Puzzle solution SP7 Albert is 7 and Carla is 13 Puzzle solution SP8 a The largest even number is FIVE THOUSAND b The largest odd number is SIXTY ONE Puzzle solution SP9 Monday N x p = £63 and Tuesday 28 x 63/N = N, So N= Ã(28 x 63) = 42 So total number of tiles = 70, So the room is 5 tiles wide Puzzle solution SP10 1888 uses 13 characters MDCCCLXXXVIII - can you better that?

Puzzle solution SP14 25 squared plus 37 squared. Puzzle solution SP15 n = 30 in base 12. This makes each part correct. Puzzle solution SP16 (9/12) + (5/34) + (7/68) = 1 Puzzle solution SP17 Let the time be x min past 10. Therefore (x - 40) = 2(60 - x), So 3x = 160 so x = 53min 20 sec. So the time is 10:53 and 20 seconds. Puzzle solution SP18 You would be writing the number 2497 when you wrote the 700th 7 Puzzle solution SP19
Puzzle solution SP20 A ---- If the number is divisible by 3 it can be made with 6 and 9 packs, except for 3 B ---- If the number is not divisible by 3 then you can use a 20 pack. C ---- Use a second 20 pack which means this remainder will be divisible by 3. So use method A. This means the largest number of books possible is 2 lots of 20 plus 3 i.e. 43 Puzzle solution SP21 Sunday Puzzle solution SP22 All 3 faces single colour - red (1), white (1), yellow (1) Puzzle solution SP23 The paios are 26 metres and 38 metres square
