This is impossible as we know that odd no.+ odd no. = even no.
?+?+?+?+? = 30
hence, upto 4 blanks the sum formed will be even.
even no. + ? =even no.(30 is even no.)
? = even no. - even no. 
hence, one even no. is fill the blanks
but we require all the odd no.s 
hence question is incorrect

The blanks couldn't be filled because the sum of odd numbers is never an even number!It could only be possible when the numbers are repeated.For eg- 1=1=2,3+3=6 etc.

i told you that the sum odd number can be even do u suppose that ur ans is best
not necessary for the numbers to repeat...
3 + 9 =12
