Answer 1

Answer:

To Form the greatest six digit odd number and smallest six digit even number using the digits from 1 to 9 only once.

It is not clear in the question that repetation is allowed or not,or it says that use 1,2,3,4,...9 only once

case 1: Repetation is allowed

Greatest 6 digit odd number= 999999

Smallest 6 digit even number=222222

Sum of both=

\begin{gathered}999999 \\ 222222 \\ - - - - - \\ 1222221 \\ \end{gathered}

999999

222222

−−−−−

1222221

case2: Repetation is not allowed

Greatest 6 digit odd number= 987653

Smallest 6 digit even number=123456

\begin{gathered}987653 \\ 123456 \\ - - - - \\ 1111109 \\ \end{gathered}

987653
