Question: How can you create an equation made up of only eight of number 8 and any number of ‘plus’ signs to equal 1000?
- How can you add eight ‘eights’ to reach one thousand?
- How can you add eight 8s to reach 1,000?
- N/A
Question Details:
You are looking for the interviewee’s logic and math skills to think of the answer.
Warning: This question has been overused or become popular enough that a large number of people know the answer to the question without having to work out the answer on their own. Therefore, caution is advised against using this question as it may not be able to measure what it was originally intended to measure. You could try a variation of this question instead.
A red flag is if the interviewee gives up and does not attempt to figure out an answer and simply says ‘I don’t know’.
888+88+8+8+8=1000
Firstly, the digit in the one’s place must be a zero, which can be most easily achieved with 8*5 = 40. This means that there should be five ‘8s’ in the one’s place being added together.
The basic equation looks like “8+8+8+8+8”. So that is five of the eight ‘8s’ used.
Working with a 40 as a necessary number, then 4 is first digit in the ten’s place. To get to the closest zero in the ten’s place is to then add two ‘8s’ to get, 4+8+8 = 20, in the ten’s place. These two ‘8s’ can be added in the ten’s place to the original row of five’8s’ added together.
The equation now looks like “88+88+8+8+8”. This is now seven of the ‘8s’ used.
Working with 20 as the necessary number in the ten’s place, then 2 is the first digit in the hundred’s place. To get to the closest zero in the hundred’s place is by added one ‘8’ to get 2+8 = 10, in the hundred’s place. This last ‘8’ can be added in the hundred’s place to the ongoing equation.
The equation now looks like “888+88+8+8+8”. Now, all eight of the ‘8s’ are used, and this equation also equals “1000”.
