Multiply the digit at column 1 by 160,000 and add the digit at colum 2, then subtract 4 times the digit at column 5, then add 2 times the digit at coumn 6, then subtract the digit at column 7, then divide by 80,000 then add the sum of digits at column 5 and column 6 to get the digit at column 11.

Once you get the digit at column 11, take the square root of that digit and multiply by 9. Multiply the number with itself and divide by 8. Divide this number by 3 and add the digits left. Subtract this sum by what you had got at column 11 and that makes column 12.

RahulG31, may be I am still not awake enough, but is there really some logic behind the long mathematics you just mentioned, or the solution is just as simple as OVERLAY for this query with 81?

more than ram_vizag's query

which did not explain where the '81' was from and someone who has been a member for 8 years should know how to post. He deserved to have his post deleted.

Ram,
In addition to using code tags where appropriate, one of the attributes of a good post is not only the input and desired output, but also the RULE defining how you get from input to desired output. You left out that last rule.

The original idea invented by Lewis Carroll:
How to calculate (2 + 1)?

Quote:

"Two added to one--if that could but be done,"
It said, "with one's fingers and thumbs!"
Recollecting with tears how, in earlier years,
It had taken no pains with its sums.

"The thing can be done," said the Butcher, "I think.
The thing must be done, I am sure.
The thing shall be done! Bring me paper and ink,
The best there is time to procure."

The Beaver brought paper, portfolio, pens,
And ink in unfailing supplies:
While strange creepy creatures came out of their dens,
And watched them with wondering eyes.

So engrossed was the Butcher, he heeded them not,
As he wrote with a pen in each hand,
And explained all the while in a popular style
Which the Beaver could well understand.

"Taking Three as the subject to reason about--
A convenient number to state--
We add Seven, and Ten, and then multiply out
By One Thousand diminished by Eight.

"The result we proceed to divide, as you see,
By Nine Hundred and Ninety Two:
Then subtract Seventeen, and the answer must be
Exactly and perfectly true.

"The method employed I would gladly explain,
While I have it so clear in my head,
If I had but the time and you had but the brain--
But much yet remains to be said.

"In one moment I've seen what has hitherto been
Enveloped in absolute mystery,
And without extra charge I will give you at large
A Lesson in Natural History."

In his genial way he proceeded to say
(Forgetting all laws of propriety,
And that giving instruction, without introduction,
Would have caused quite a thrill in Society),
