The given numbers are all odd. The sum of 5 odd numbers must be odd. 50 is not odd so there is no solution.
There are no four odd numbers that will add up to nineteen.
3, 7 and 9. 4 odd digits that add up to 19 would be 9, 9, 0.5, 0.5
It is not possible to add together 5 odd numbers to make an even number.
that question cant be answered unless it was 3 odd-digits or 4 odd-digits with 1 even digit i think.

It is impossible. The digits are all odd. Adding six odd digits gives an even digit so their sum cannot be 21.
It is even. Both numbers end with odd digits and two odd digits always add to an even number. You can see that is the case in this instance.377 + 87 = 464

1.5 and 1.5 easy peasy
You cannot add 4 odd NUMBERS to make an odd number, so you have to think constructively...eg 1 + 3 + 15 = 19. There are other similar solutions...
This is impossible. 21 is an odd number and all these digits are odd. Whenever you add 6 odd numbers together, the answer is always even!
