What three odd integers native the set 1,3,5,7,9,11,13,15 that once summed together equals to 30? note that any kind of integer have the right to be used much more than once.

You are watching: Three odd numbers that add up to 30

Is there any possibility to deal with these sort of questions with part formulae? keep in mind I have gone through the answers for making it v 5 numbers.


Note the all the elements of the collection are odd.

Hence, even if us repeat, us have, w.l.o.g, the following cases

(i) weird $x$ + strange $x$ + odd $y$ = Even+Odd=Odd

(ii) weird $x$ + odd $y$ + odd $z$ = Odd

(iii) strange $x$ + strange $x$ + odd $x$ = Even+Odd=Odd

.... If $30$ is even.

I in reality remember this question which is rumored to it is in from one IAS exam and no one can solve it other than the topper. That"s actually a false rumor.

The only method you can acquire $30$ is by doing it in a snucongo.orgematically incorrect way (by a "trick"), choose $7.5+9.5+13=30$

Other 보다 that, this question just is a bogus question.
