Which one is greater on Richards farm: the total number of pigs and horses, or the number of chickens?
(1) The ratio of the number of chickens to the number of pigs to the number of horses on his farm is 33 : 17 : 21.
(2) The total number of chickens, pigs, and horses on his farm is 142.
So I was wondering if there was some kind of general principle on what kinds of assumptions you can on DS questions. I know the general rule is 'make no assumptions', but that is not 100% true. Now, this particular problem is from Nova, but it goes:
For this problem, can I assume that there exist more than 0 pigs, horse, and chickens? According to the solution, you are supposed to, but there's nothing that would indicate to that notion. I'm not sure if this is something I should worry much about or not. Thoughts?![]()
