Pdf Summary
The Math Kangaroo competition in 2019 for Levels 3 and 4 presented a series of challenges, each requiring careful analysis to solve. Here is a condensed summary of the solution suggestions provided:<br /><br />1. **Sequence of Runners**: The correct positions involve placing the runner with "D" on the highest step, followed by "B" and "E".<br />   <br />2. **Picture Representation of Numbers**: Picture (C) represents the number 12.<br />   <br />3. **Day Calculation**: If yesterday was Sunday, today is Monday, and tomorrow is Tuesday.<br /><br />4. **Vehicle Visibility**: Olaf sees specific vehicles based on his view when the book is closed, revealing the second, fourth, and fifth from the left.<br /><br />5. **Adjacent Puzzle Pieces**: Karina can acquire only the piece with a star and club as indicated.<br /><br />6. **Footprint Order**: Analyzing shoe prints reveals a unique walking order, answered by choice (A).<br /><br />7. **Stick Count**: Pia’s shape contains 10 connected sticks; only option (D) features a shape with 12 sticks.<br /><br />8. **Math Operations**: Solving the given sequence results in the number 5.<br /><br />9. **Pin Usage**: Pinning 7 photos requires 16 pins.<br /><br />10. **Shape Formation**: Dennis can form three specified shapes from a set.<br /><br />11. **Stripe Observation**: A specific configuration of stripes is depicted in choice (C).<br /><br />12. **Dog’s Weight**: The dog weighs 11 kg, meeting conditions outlined by two scales.<br /><br />13. **Strategy Puzzle**: Solution involves calculation but is not detailed.<br /><br />14. **Digit Formation**: Maximum sum with specific conditions yields last digit options of 0 or 1.<br /><br />15. **Water Weight Calculation**: A half-full glass weights 250 grams.<br /><br />16. **Fruit Cost Analysis**: Identifying individual costs results in a total of 11 cents.<br /><br />17. **Shape Values (Arithmetic Puzzle)**: The analysis determines that a star is represented by the number 6.<br /><br />18. **Square Count in Frame**: A frame with specific dimensions requires 44 squares.<br /><br />19. **Page Number Calculation**: Determining the inclusion of digit 5 concludes at page 64.<br /><br />20. **Path Length**: A combined horizontal and vertical path measurement equals 83 meters.<br /><br />21. **Animal Distribution Problem**: After exclusion deductions, 3 kangaroos remain.<br /><br />22. **Triangle Color Assignment**: Triangles 1 and 3 are determined to be yellow based on adjacency constraints.<br /><br />23. **Cookie Eater Deduction**: Statements reveal Bartek as the one who ate the cookie.<br /><br />24. **Hanging Towels with Pegs**: Correct peg allocation for hanging 35 towels indicates using 58 pegs when 22 towels are hung using the first method. <br /><br />These solutions involve applying logical reasoning and simple arithmetic, crucial for students in mathematical problem-solving contexts.
