應(yīng)該是A是B的兩倍,所以
第一個(gè)小孩是女孩,所以她看家里就是 4個(gè)男孩,2個(gè)女孩,所以brothers是sisters的兩倍
第二個(gè)小孩是男孩,所以他看家里就是 3個(gè)男孩,3個(gè)女孩,所以,brothers 和sisters 一樣多
看到類(lèi)似的題,先邏輯分析一下,可以判斷出第一個(gè)小孩是女孩,第二個(gè)小孩是男孩,接下來(lái)就容易了
假設(shè)男孩總數(shù)是X,女孩總數(shù)是Y
第一個(gè)女孩看到的是：x=2(y-1)
第二個(gè)男孩看到的是：(x-1)=y
然后解一下,x=4,y=3 這樣就大功告成了!

During a visit by the census taker,one child in a
family said,“I have twice as many brothers as sisters.”
Another child in the family said,“I don’t.I have the
same number of brothers and sisters.” How many
children are there in the family?
題目中有一句 “I have twice as many brothers as sisters.”我上網(wǎng)查了一下twice as many A as 之前的前輩都說(shuō) B是A的兩倍.但是這道題最后的答案是 4 boys 和 3 girls,總共7個(gè)小孩,這樣子的話,那句的意思就是brothers是sisters的兩倍咯?
糾結(jié)了很久
