Actually, they have asked largest 5 digit number which is devisable by 91, if we add the difference of deviser and quotient that is 10 then it will definitely divide by 91 but it is a six-digit number.

So, if substract 99999 by 81 then the value is 99918 which is the largest 5 digit number divisible by 91.

99918 should be the correct answer.

Largest 5 digit number always 99999.
Easy to remind 9x9=81.
So 99999-81=99918.

Why not the remainder was subtracted from quotient and then added to the number?

You are correct, Thanks @Gooner8.

No it is not divisible by 91 @Anm.

99999 itself is divisible by 91? Then why 99999 is not that number?

If 10 is added it becomes 6 dig number 99999.

= 100009.
