Before seeing the clues,
estimate the length of the
yarn – when it is straightened
– in centimeters.
As the clues appear, use the
information to narrow the
possibilities to a smaller set.
Then use estimation to
determine which of the
remaining answers is the
most reasonable.
Clue #1
Clue #2
Clue #3
Clue #4
Clue #1
The answer is between 45 and 125.
Clue #3
The answer is not a multiple of 10.
Clue #4
The answer does not include the
digit 4.
Clue #2
Look carefully at the cm side of the
ruler. The yarn is touching a
pattern of numbers – except it
missed a number in that pattern.
The answer is a multiple of the
missing number.
