Question 832213: how I add any 5 odd number which is lie between 1 to 20 and sum of that 5 number is 50...

You can put this solution on YOUR website! Maybe something got lost in translation, and I am misinterpreting your question.
By "odd" we usually mean not divisible by 2, and we call even the numbers that are not "odd" by that definition.
The odd numbers between 1 and 20 are:
1 (if you include the 1 and 20 in the "between 1 and 20"),
3, 5, 7, 9, 11, 13, 15, 17, and 19.
The numbers 2, 4, 6, 8, 10, 12, 14, 16, 18, and 20 are even.
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. You could use 4 odd numbers and an even number, or 2 odd numbers and 3 even numbers, or 5 even numbers. No other combination will work.
