Math Brain Teaser

This Monday we brought to you a burning brainteaser. Err… not exactly burning but those matchsticks must have surely sparked your head. So, here we are with the much-awaited solution.

The Solution

Brainteaser Monday 18Jan16


24 matchsticks were arranged in such a way that they formed the number 5008. Now the brainteaser asked us to move just two matchsticks and form the highest possible numbers.

One said its 6009, another replied it was 9800. But unfortunately, both were wrong. The thing with such brainteasers is, they often require a little out of the box thinking. Same was with this one.

Let us have a look at the arrangement one more time.

5008 MatchstickNow, we can only move two matchsticks. So what we are going to do is, take the two matchsticks on top and bottom of the second zero and place them vertically like this.



Monday Brainteaser Solution 18JanSo we now have the number 501,118. But we have not yet arrived at the highest number. To arrive at the highest number just turn the point of view 180 degrees in clockwise direction and you will have your answer.

Monday Brainteaser Solution 18JanYes, the answer is 811,105.

Amazing right!
