The sum of the greatest and smallest six digit numbers that can be formed the digits 5, 9, 0, 2, 8 and 6 (without repetition) is:

Given: digits 5, 9, 0, 2, 8 and 6

Smallest number:
The digits in ascending order are: 0, 2, 5, 6, 8, 9.
Since the number cannot start with 0, we place 2 at the first position.
The smallest number formed is: 205689.
Greatest number:
The digits in descending order are: 9, 8, 6, 5, 2, 0.
The greatest number formed is: 986520.
Sum of the greatest and smallest numbers: 205689 + 986520 = 1192209
Correct answer is (b) 1192209.
