This person owns just 2 sand timers.

Using the timers, they measured various amounts of time in the shortest way possible.

It took 6 minutes to measure 1 minute, 5 minutes to measure 2 minutes, and 3 minutes to measure 3 minutes.

Which 2 timers do they own?

As an example, if you used the 3 and 4 minute timers, the 4 minute timer would have 1 minute left to run when the 3 minute timer finished.

It would take 4 minutes to measure 1 minute.

Hint 1

Try to exclude the timers that can't be used so that you cn narrow down the ones that were.

For example, if it took 6 minutes to measure 1 minute, that means that the 1 minute timer can't have been used as that would have taken just 1 minute in total.

Hint 2

It took 5 minutes to measure 2 minutes.

This would have taken just 2 minutes with the 2 minute timer, which means that this timer can't have been used.

Hint 3

It took 3 minutes to measure 3 minutes.

This would be possible by using the 3 minute timer once or the 1 minute timer 3 times.

We already know the 1 minute timer was not used, so that means the 3 minute timer must have been used here.

Super Hint

If you use the 3 minute timer twice, it takes 6 minutes.

Look at the 4 minute timer and the 5 minute timer and work out which of them would fit in with the details in the question.
