I am sorry but we have been taught in the primary that the sum of any odd numbers taken odd times is never even.Its a mathematical fact and you can't break it just as 1+1=2, you cant say its 1+1=3(its false). So, We can't get 30 by adding odd number odd times but it can be surely like this:
1+3+11+15=30
1 5 1
Hope this helps!
Yup! I too guess that we cannot get the answer n the thing is I'VE asked to some of friends they said that it won't come, otherwise any condition must be given there
