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
