Why do I care if none of the numbers are greater than 60 couldn't I just say
x+x+9+10/4=30?
x+x+9+10/4=30?

Okay let's say you can say that:vladmire wrote:Why do I care if none of the numbers are greater than 60 couldn't I just say

2x= 120-19
2x = 101 ( By the way you just assumed that remaning two numbers are equal )
x = 50.5 and B is the answer in your case
BUT
the question says FOUR DIFFERENT numbers
so X+Y =101
we are trying to find the numbers > 30
Lets say they are both bigger than 30
50 + 51 BINGO
or one of them is less than 30
29 + 72 BINGO
so we have two different answers ( they both cannot be less than 30 )
SO INSUF
But statement A gives us a clue: None of the numbers are > 60
so 29, 72 wont work.
lets try 60
60+41 , so 2 numbers are greater than 30
Can we get only one number greater than 30 ? No we can not!
So answer is 2 numbers!
And we need both statements, so C will be the correct answer
