Challenging riddles and puzzles excite our brains.
If you are one of those people who enjoy working on puzzles and do not rest unless you have the answer, here's a tricky one for you. This IQ test is prepared by Mensa International, UK.
I see a question mark there. What number out of the given options should replace it? 10,8,5,3, or 2?
Are you sure, it should be 5 there?
It is an IQ test, not an algebra problem!
Nops, keep trying...
It is not 5, it is not 10. Then what is it?
Take this hint. Don't have an answer? I cannot wait.
The answer is 2. Here's how:
Look closely at the series. The sum of the numbers in each slice of the outer ring makes a place in the next slice of the inner ring. For example, the sum of 4 and 2 in the slice having a question mark is 6 and is displayed in the inner ring of the next slice, moving clockwise. You got it!
Go on, challenge your friends and test their IQ.
