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. <strong>Sequence of Runners</strong>: The correct positions involve placing the runner with "D" on the highest step, followed by "B" and "E".<br />   <br />2. <strong>Picture Representation of Numbers</strong>: Picture (C) represents the number 12.<br />   <br />3. <strong>Day Calculation</strong>: If yesterday was Sunday, today is Monday, and tomorrow is Tuesday.<br /><br />4. <strong>Vehicle Visibility</strong>: 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. <strong>Adjacent Puzzle Pieces</strong>: Karina can acquire only the piece with a star and club as indicated.<br /><br />6. <strong>Footprint Order</strong>: Analyzing shoe prints reveals a unique walking order, answered by choice (A).<br /><br />7. <strong>Stick Count</strong>: Pia’s shape contains 10 connected sticks; only option (D) features a shape with 12 sticks.<br /><br />8. <strong>Math Operations</strong>: Solving the given sequence results in the number 5.<br /><br />9. <strong>Pin Usage</strong>: Pinning 7 photos requires 16 pins.<br /><br />10. <strong>Shape Formation</strong>: Dennis can form three specified shapes from a set.<br /><br />11. <strong>Stripe Observation</strong>: A specific configuration of stripes is depicted in choice (C).<br /><br />12. <strong>Dog’s Weight</strong>: The dog weighs 11 kg, meeting conditions outlined by two scales.<br /><br />13. <strong>Strategy Puzzle</strong>: Solution involves calculation but is not detailed.<br /><br />14. <strong>Digit Formation</strong>: Maximum sum with specific conditions yields last digit options of 0 or 1.<br /><br />15. <strong>Water Weight Calculation</strong>: A half-full glass weights 250 grams.<br /><br />16. <strong>Fruit Cost Analysis</strong>: Identifying individual costs results in a total of 11 cents.<br /><br />17. <strong>Shape Values (Arithmetic Puzzle)</strong>: The analysis determines that a star is represented by the number 6.<br /><br />18. <strong>Square Count in Frame</strong>: A frame with specific dimensions requires 44 squares.<br /><br />19. <strong>Page Number Calculation</strong>: Determining the inclusion of digit 5 concludes at page 64.<br /><br />20. <strong>Path Length</strong>: A combined horizontal and vertical path measurement equals 83 meters.<br /><br />21. <strong>Animal Distribution Problem</strong>: After exclusion deductions, 3 kangaroos remain.<br /><br />22. <strong>Triangle Color Assignment</strong>: Triangles 1 and 3 are determined to be yellow based on adjacency constraints.<br /><br />23. <strong>Cookie Eater Deduction</strong>: Statements reveal Bartek as the one who ate the cookie.<br /><br />24. <strong>Hanging Towels with Pegs</strong>: 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.
