There was this question that I got wrong that asked:

The eggs in a certain basket are either white or brown. If the ratio of the number of white eggs to the number of brown eggs is 2/3, each of the following could be the number of eggs in the basket EXCEPT:

10

12

15

30

60

I answered 10 thinking that 2/3 * (answer) should give an integer. WRONG

The answer is 12.

So the ratio must have been 2 to 3 in the sense that 2+3 is 5 so the answer must be divisible by 5.

BUT how do I know whether the ratio is in the sense that x+y should be divisible by the answer or x/y should be divisible...

I am really looking forward to getting some replies because I am stuck
