How our Riddles Work

How to solve our Metric Unit Riddles

Each of our riddles consists of a set of clues and 8 possible answers.

In order to solve the riddles and find the solution, follow these simple steps:

  • Work your way through the clues
  • After each clue, cross off any of the possible answers that are invalidated by the clue
  • Once you have completed all the clues, there should just be one possible answer left which has not been crossed out.
  • This is the solution to the riddle!

We have created two versions of each riddle: one version with the relevant conversion facts included and one version with no conversion fact support.

Solving a Customary Units Riddle Example

We will show you the steps to solve a basic measurement riddle with just 6 possible answers below.

converting customary units riddle example 1a

Let's start with the first clue: I am more than 2 cups.

If we look at all of the possible answers, then all of them are more than 2 cups except for two.

The two answers which are incorrect for this clue are:

  • 1 cup 6 fluid ounces
  • 7 fluid ounces (as 1 cup = 8 fluid ounces)

We cross off both these answers from our possible answers list.

We can also tick off the first clue.

converting customary units riddle example 1b

Now we move on to the next clue: I am less than 2 pints.

We can see that this time, just one of the measurements is not less than 2 pints which is 5 cups (1 pint = 2 cups).

So we can cross off this answer from our list, along with the second clue.

converting customary units riddle example 1c

Moving on to the third clue: If you round me to the nearest pint, I round down.

We know that 1 pint = 8 fluid ounces and 1 cup = 4 fluid ounces.

This means that if the measurement is 4 fluid ounces more than the pint value (or more) then it rounds up, otherwise it rounds down.

There are 3 measurements left:

  • 1 pint 3 fl oz. which rounds down to the nearest pint (since it is only 3 fluid ounces more than a pint)
  • 3 cups 2 fl oz. = 1 pint 1 cup 2 fl oz. = 1 pint 6 fluid ounces which rounds up to the nearest pint since it is more than 4 fluid ounces bigger than 1 pint.
  • 1 pint 7 fl oz. which rounds up to the nearest pint.

This means that we can cross off the two incorrect answers from the list.

converting customary units riddle example 1d

We have finished all the clues and we only have one possible answer left, so we have found the solution to the riddle.

The final answer to the riddle is: 1 pint 3 fl oz.
