Let first digit be 'X' then 5th digit is '3X'
Let 2nd digit be 'Y' then 3rd digit is 'Y-3' and 4th digit is 'Y+4'
then the number is '(X)(Y)(Y-3)(Y+4)(3X)'
From the above we can say 3X<=9 so X<=3 and any of the digit in the number is
<=9 and also given that 3 pairs sum is 11...
so make trial and error..
If X=1...any of the number is 10 which is wrong trial....
If X=2...then let Y+4=9 ==> Y=5 then number is 25296
First pair 2+9=11
Second pair 2+9=11
Third pair 5+6=11
Now the answer is 25296
