<p>This question was so easy why did 62 percent get it wrong?????????</p>
<p>because they answered 9. instead of just listing the DIFFERENT combinations, they just did 1+4, 1+5, 1+6, 2+4, 2+5, etc., and some of those combinations equal the same answer. they were just lazy and counted it like that instead of doing the simple math</p>
<p>the simple way of doing this is just adding the smallest value together which is 1 + 4 = 5, and the largest values which is 3 + 6 = 9, from column to column. Then you simply count the integers from 5 to 9 inclusive, which is 5 integers, so five different sums. The answer is E. This works only if the numbers in the columns are consecutive integers.</p>
<p>I don't think "lazy" would be the right word.
I don't think they were thinking of the word "values" throughly. But, I got that one wrong =(</p>
<p>Sorry, but not everyone is as good as you.</p>
<p>I clicked on the link and it said I got it wrong, when I hadn't even typed in anything. Bastards.</p>
<p>akahmed, great advice. Thanks.</p>
