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%
根據(jù)答案的推理,學(xué)習(xí)西班牙語的人數(shù)是64.
但是我為什么算出來學(xué)習(xí)西班牙語的人是128,
假設(shè)學(xué)習(xí)西班牙語的人數(shù)是X,那么
因為120= 24+ X-32
X= 128
可是總?cè)藬?shù)才120啊,我的思路哪里有問題了?
打錯了~
