Question

_ + _ + _ = 30 using ( 1,3,5,7,9,11,33,15,17,19,21,23,25,27,29)

Answer 1

IF two odd numbers are added, it will give an even number. If an even number is added to an odd number, it will given an odd number.
So, adding three odd numbers will give you an odd number.
So, this is not possible. Result "30", is not possible.
Eg:-   3+5=8  3+5+7=15. 
So, 4! +1+5=30. (You can do it in this way).

Thank you.
Hope this will help you.

Answer 2

 so, it is possible only in case of factorial.
3! + 11 + 13 = 30

hope its help u
