To solve this question you need to use decimals. You can't make an answer just by adding any of those 3 whole numbers as they all are odd numbers. So by using decimals you can overcome the above said problem.

And the answer is

**

**13.573 + 9.3111 + 7.1159 = 30**

Note: No numbers used outside from the List

This question is unsolveable.No three or five or seven odd numbers can be added to give an even number.Three odd numbers added together will always give an odd number yet the result in this solution is even(30)

I think the best solution will be to use two odd number,example, 15+15,or else we can use four odd numbers,example, 13+11+3+3=30.
