This is not mathematically possible

Logic Level 2

Following is a grid with 8 boxes: Fill the grid with the number 1-8 in such a way that:

  • 2 should not be near 1( that is:up,down,diagonal,right and left)

  • 3 should not be near 2( that is:up,down,diagonal,right and left)

  • 4 should not be near 3( that is:up,down,diagonal,right and left)

  • 5 should not be near 4( that is:up,down,diagonal,right and left)

  • 6 should not be near 5( that is:up,down,diagonal,right and left)

  • 7 should not be near 6( that is:up,down,diagonal,right and left)

  • 8 should not be near 7( that is:up,down,diagonal,right and left)

For example, if you fill 1 here,then 2 cannot be in the boxes with crosses: Input your answer as follows, for example if this is your answer, then you should type: 12345678

Ps. There are 2-3 possible answers, I have just put the most common one, don't feel insulted if you find your solution was correct but just a reverse of mine. So, beware try all the 2-3 possible solutions

The answer is 35718246.

I think, there can be multiple answers for this question like:- 64281752 64281752 , 46718235 46718235 , 53281764 53281764 .There are more than one answers. Take care next time. good question though. From where do you get these amazing questions?

Ashish Menon - 5 years, 3 months ago

Yes, you are right. I was lucky to have entered the right answer in the first go itself!

Hey you at least praise the question rather than felling lucky and top of the world first

Rishabh Sood - 5 years, 3 months ago

Log in to reply

@Rishabh Sood Haha! No doubt the question is good.

However, as Ashish Siva has already pointed out earlier, there are four answers : 35718246 and it's laterally inverted counterpart, i.e., 53281764, and 46718235 and it's laterally inverted counterpart, i.e., 64281753.

So.. yea, I'm lucky enough to have chosen the "right" answer out of the 4 correct ones.
