Answer 1

Step-by-step explanation:

$\underline{\underline{\huge{\blue{\tt{\textbf Answer :-}}}}}$

If you add any 5 of those numbers the sum will always be odd. It could be 49, or 51, but it can never be 50.

If you add an odd number (like 5) of odd numbers, the sum is always odd.

You could add 5 numbers between 1 and 20 and get a sum of 50, but they cannot be all odd numbers.
