NMOS二轮模拟题修正

NMOS二轮模拟题修正

6月25日上周六模拟考试时曹老师在《奥数是个什么东西》讲座后发放了《NMOS3+3+3》，其中有二轮模拟题中有两道题目的题干信息有误，特此修正：

第18题的题干信息应为：

There are cats, dogsand other animals living in a strange animal village. 20% of dogs think theyare cats while 20% of cats think they are dogs. Other animals are normal. Oneday, the little monkey, the village head of the animal village, found thatamong all the cats and dogs, 32% of them think they are cats. If there are 180more dogs than cats in this strange animal village, how many dogs are there?

第19题的题干信息应为：

As shown in thefigure, square ABCD has three vertices on three sides of triangle EFG, and BE=BF. Find the area (in cm2) of the square ABCD. [附件不存在]

希望大家做题时注意修正，同时也对因此给大家造成的不便深表歉意。

特此更正。
