Of the 60 animals on a certain farm,
are either pigs or cows.How many of the animals are cows?

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

(2)The farm has more than 12 pigs 有条件1 可知是牛的数量比猪的数量2倍还多 C>2P 那么如果是C=2P 那么句子应该怎么说呢？我刚做题的时候算成了后者细小的差别怎么看出来呢求指点

肯定选E，你想想，就算P=15，C=35, 总数也小于60，则此时C=35,36,37都可以
