Answer 2

Answer:

The sum of the greatest 6 digit odd number and smallest 6 digit even number is 1099999

Step-by-step explanation:

We know,

Odd numbers are the numbers that are not divisible by 2

Therefore,

The unit digit of odd number should be either 1 or 3 or 5 or 7 or 9

So, The greatest 6 digit odd number that can be formed = 999999

Similarly,

We know,

Even numbers are the numbers that are divisible by 2

Therefore,

The unit digit of odd number should be either 0 or 2 or 4 or 6 or 8

So, The smallest 6 digit odd number that can be formed = 100000

Sum of these numbers = 999999 + 100000

Sum = 1099999

Hence,

The sum of the greatest 6 digit odd number and smallest 6 digit even number is 1099999
