Pdf Summary
The document is a series of solution suggestions for the 2020 Math Kangaroo competition, targeting levels 5-6. It consists of multiple-choice questions followed by detailed explanations of the solutions. A summary of the key solutions includes:<br /><br />1. **Question 1 (E)**: The correct piece includes a quadrant of the circle and two kite-shaped spikes, matching the corner of the square.<br />   <br />2. **Question 2 (E)**: All signposts except (E) show a distance of 11 km between two towns, making (E) incorrect.<br /><br />3. **Question 3 (D)**: After changing the colors from gray (G) and white (W), the revised pattern matches that shown in option (D).<br /><br />4. **Question 4 (B) 2**: To bake 24 muffins, Mikas needs an additional pair of eggs, requiring a total of 2 boxes of eggs.<br /><br />5. **Question 5 (E)**: The reflected image of letter F along both vertical and horizontal lines matches option (E).<br /><br />6. **Question 6 (C) 13**: Kim cannot create a chain of length 13 using given lengths of 5 and 7.<br /><br />7. **Question 7 (A) 3**: Maria needs to cut 3 sheets to obtain 22 pieces of paper.<br /><br />8. **Question 8 (B) 3**: In the pattern, choosing red for x results in 3 red and 2 yellow regions, with 3 blue regions.<br /><br />9. **Question 9 (C) 5**: Moving apples for evenly distributed baskets requires moving a minimum of 5 apples.<br /><br />10. **Question 10 (E) at E**: A comparison of the paths shows that the dog and cat meet at point E.<br /><br />11. **Question 11 (A) 3**: The sum logic helps in placing the missing numbers correctly in the circular puzzle.<br /><br />12. **Question 12 (E) 5h 42m**: Elise was absent for 5 hours and 42 minutes based on the clock configuration.<br /><br />13. **Question 13 (A)**: The statement "I am telling the truth" can be made by both a liar and a truth-teller.<br /><br />14. **Question 14 (B)**: Cube (B) corresponds to the materials and assembly Mary possesses.<br /><br />15. **Question 15 (C)**: Route (C) is the shortest due to minimal segment lengths.<br /><br />16. **Question 16 (C) 7**: After 7 years, the children would hold the majority of votes.<br /><br />Remaining questions (17-30) follow a similar pattern of logical deduction and numerical calculations, ensuring that each identified solution corresponds correctly with the problem statements. The answers utilize analysis, arithmetic calculations, and logical reasoning to determine correct solutions, promoting understanding among the intended audience.
