1). The farm has more than twice as many cows as it has pigs -->at most, there are 13 pigs, but not sufficient alone

how is it inferred that pigs are at most 13.

is it c= 2p

c or p =40

Of the 60 animals on a certain farm, 2/3 are either pigs or cows -

c+p =2/3 * 60 =40

1). The farm has more than twice as many cows as it has pigs.

2). The farm has more than 12 pigs

If we combine stat 1 and stat 2, then

p>12

c>2p

Lets consider p=14, then c would be greater than 28(2x14=28)

14+29=43 -not correct because c+p =40

only if p=13 then c can be(greater than 13x2=26) 27

therefore C is the answer.

Hope my post is helpful.
