Today’s brain teaser is definitely a head scratcher and will make you think back to the last time you were in a classroom learning maths. If you have just finished your GCSEs or are Rachel Riley from Countdown then you will definitely have an advantage, not least because you will remember what “integer” means.

If you can solve it within 15 seconds, and without having to brush off your mathematics skills from school, then you have a high IQ.

But don’t worry if you have struggled because we will reveal the solution below.

All you have to do is work out what is the smallest integer greater than 95,555 in which there will be four identical numbers?

The first step is to remind yourself what the word “integer” means.

In maths, an integer is a whole number (not a fractional number) that can be positive, negative or zero.

Some examples of integers are -5, 1, 97, and 4,076.

And of course, the number in the puzzle, 95,555, is also an integer.

All you need to do to find the answer is to think of numbers greater than 95,555 where there are four identical numbers.

One example would be 96,666 because there are four sixes and 97,777 because that number contains four sevens.

But neither of them are correct because the solution is the smallest integer greater than 95,555 and although it might seem like that’s 96,666, that’s not quite right.

Some people will have been able to instantly look at the question and work out the answer.

Everyone else should have one last go at trying to solve the problem before looking at the solution which is revealed below.

The answer is 95,999 because the final three digits are nines and the first digit is also a nine. Puzzles like this are definitely much easier when you know how.

Brain teasers like this may seem like they are just a brief distraction but some experts suggest doing just one or two a day could have benefits in the long run.

If you do them repeatedly alongside other mental exercises such as crosswords, this could help improve your brain health in the long run.

The brain is a muscle, and like other muscles in the body, it needs to be exercised. The healthier and fitter your brain is, the less likely you are to develop a neurodegenerative condition such as dementia.

While this isn’t to say that brain teasers will stop you from getting dementia, other factors play a role too, they could help keep your brain healthy.
