Answer 1

Answer:

❏ Appropriate Question :

• Find the sum of the greatest and the least six digit numbers formed by the digits 8, 0, 9, 7, 6, 4 using each digit only once.

❏ Solution :

So there are 600 six-digit integers that can be made from the digits 8 6 2 0 4 9

$\sf\pink{ (integers \: starting \: with \: zero \: are \: 5-digit \: integers).</p><p>}$

Now subtract the smallest integer in b from the largest integer in b, separate the digits of the result, and sum the digits:

$\sf\pink{+/sep(>./b)-<./b</p><p> \: 27}$

❏ Hence,

The answer is 27..
