Question

Find the sum of the greatest and the least six digit numbers formed by the digits 2, 0, 4, 7, 6, 5 using each digit only once.

Answer 1

Given digits are 2, 0, 4, 7, 6 and 5.

Using each digit only once,

The greatest six-digit number = 765420

The smallest six-digit number = 204567

Now, the sum of these numbers = 765420 + 204567 = 969987
