Each group contains two watches, not just one.
This means that one watch is worth 2.
So far, we have three important values.
One pair of earbuds is worth 10.
One person is worth 5.
One watch is worth 2.
Now comes the tricky part!
Look closely at the final equation.
It shows one earbud, one person, and one watch.
However, there is something different
about the earbud.
The earlier equations show a pair of earbuds, while the final equation shows only one earbud.
Therefore, we must divide the value of a pair by 2.
One earbud is worth 5.
The person is still worth 5, and the single watch is still worth 2.
But don’t rush to add these numbers together!
There is one final rule to remember.
In mathematics, multiplication must be performed before addition.
This means we must multiply the value of the person by the value of the watch first.
Five
multiplied by two equals 10.
Then, we add the value of the single earbud.
Five plus 10 equals 15.
And there you have it!
The correct answer is 15.
The secret to solving this puzzle is to pay attention to the small differences
