Step-by-step explanation:
According to me the full questions seems like this,
If 1+3+5+7+9+11+13+15=64.
Now use any 3 numbers from the above expression such that “_ +_ +_ =30.”
Since the question is so famous because you cannot get sum of 3 odds to make an even.
I saw many people solving it like:
13.3 + 15.7 + 1 = 30.
3! + 11 + 13 = 30.
I really praise them who solved it like that, but since the actual question is the above one. So i would solve it like that.
Since,
1+3+5+7+9+11+13+15 = 64
1+3+5+7+9+11+13+15 - 64 = 0.
Now ,
1+3+5+7+9+11+13+15 + (-64) = 0
It can be written as,
64 - (1+3+5+7+9+11+13+15) = 0.
64 +(-1)+(-3)+(-5)+(-7)+(-9)+(-11)+(-13)+(-15) =0.
Now we are free to use any three values.
So we should add,
“ 64 + (-11) + (-13) = 64 + (-24) = 30”
So according to me it is the correct answer i believe.
