There is only a right or wrong answer with this quiz, but the way you answer seven cleverly crafted questions apparently can tell if you are a man or a woman.
The first question shows a controversial weight loss advert which appeared on the London Tube.
It shows a slender woman wearing a yellow bikini with the words, ‘Are you beach body ready?’.
The quiz asks, ‘Do you think this advert is offensive’ and the possible answers are ‘I have no opinion’, ‘offensive and annoying’ and ‘I’m not offended by it’.
Other questions ask how you feel about the game Candy Crush, what you thin of polyamory, whether you would want to be a librarian and whether you hate mice.
Seven questions and answers later, the test available on Playbuzz should be able to determine your correct gender.
Another test on the website is made up of variety of brain puzzles which can determine if your IQ is in the top 1 per cent.
IQ (intelligence quotient) is an assessment of your ability to think and reason.
This quiz claims only the smartest people in the world can solve all of the puzzles.
The test is made up of ten questions, but while they appear to ask simple tasks, they are much harder than you first think.
Another test offers a free eye test and claims to be able to tell you how good your vision is in only 10 questions.
Each question asks the user to pick a square that looks different to three others.
