Mensa is a society for individuals with high IQ. The community allows members to have an intellectual exchange with other members through lectures, discussions, journals, special-interest groups and gatherings.

According to Mensa's official website, the group has three goals: "to identify and foster human intelligence for the benefit of humanity, to encourage research in the nature, characteristics and uses of intelligence, and to promote stimulating intellectual and social opportunities for its members."

It was founded in 1946 in England by barrister Roland Berrill and scientist/lawyer Dr. Lance Ware. The only qualification for membership is a high IQ. Their aim is to develop a society that is "non-political and free from all racial or religious distinctions."

Mensa reportedly has more than 120,000 members in 100 countries throughout the world. There are members as young as 2 years old to more than a hundred years old, but most are between 20 and 60.

Business Insider shared some Mensa test questions and answers. It is a sample of what the elite society members had to solve to have their IQ calculated.

"The questions are similar in style to those which are likely to be included in an accredited IQ test," the publication wrote. "Although answering the mini test will not show an accurate IQ score, it can give a rough indicator of how well you may do if you attempted a Mensa IQ Test."

The Mensa test questions included questions such as "What number is missing from this sequence? 4 9 16 25 36 ? 64" and "Rearrange the letters of 'ANY TIME' to give a seven letter word. What is it?"

The answer to the first question is 49, since all the given numbers are a perfect square (2x2=4, 3x3=9, etc.). The second question's answer is AMENITY.

The Mensa test questions are a combination of language and number-based puzzles. The first test, named Cattell III B, is composed of 158 questions while the second exam, Cattell Culture Fair III A, has 50 questions, most of which are diagram-based.
