problem 596

“Here you can see last weeks drawing again”, Mike said. “It’s meant to be tried out using oranges and olives by the students who go to Paternó in Sicily to harvest oranges. The blue circles represent olives and the red ones oranges.”
The drawing shows the start of the pattern. After that it will be olives and the oranges and so on. How many olives and oranges do you need to make a pattern that has 5 riings of oranges? - 6 blue points
595 596

What does the pattern look like when you use exactly 4567 oranges (there a re enough olives). If there aren’t enough oranges for a complete “ring” you may eat the remaining ones. How many olives do you need for this pattern? - 6 red points

Solving the picture-puzzle will get you two extra blue points, provided you also got points doing the regular maths problem. The rule for each picture puzzle is: Each icon represents one digit, same icons, same digits, different icons, different digits.  ©HRGauern[at]@t-online.de
