When I doing the IQ paper last Sunday, I found an interesting question. Using that I made a different puzzle.
Hint 01:
Middle number of each row build using the number before and after it. Eg: 13 built using 25 & 43.
Hint 02:
4th row will be 55 73 73 & 5th row will be 65 36 83
Hint 03:
If the 1st and last number of any row include the same letters with opposite like 35 and 53 (3 & 5 letters are in both), a middle number will have definitely same letters like 66 (11,22,33, etc)
Hint 04:
I had done a mistake when writing last hint(last row of the grid.). I am really sorry about that, but you can get another hint from how I correct my mistake. I mean which numbers I have changed to correct my mistake... I will write the correct answer tomorrow.
Text version:
25 13 43 35 66 53 45 -- 63 55 73 73 65 36 83
