120 children are participating in a summer camp and all of them must choose at least one of the French or Spanish language workshops in which to participate.32 of the children have selected to participate in both workshops.If 24 children participate exclusively in the French workshop,approximately what percentage of all the children exclusively participate in the Spanish workshop?
A.40%
B.48%
C.50%
D.53%
E.64%
根据答案的推理,学习西班牙语的人数是64.
但是我为什么算出来学习西班牙语的人是128,
假设学习西班牙语的人数是X,那么
因为120= 24+ X-32
X= 128
可是总人数才120啊,我的思路哪里有问题了?
打错了~
