A 36岁
B 在36岁的时候,年龄是A的两倍
所以A当时18
B比A大18
所以B现在36+18=54
一个男人36岁了。他问另一个人他有多老。另一个人回答:“当我像你这么大时,你只有我的一半大。”另一个男人多大了?
就是48
注意 "I am twice ..." 用的是 am 而不是 was 。
也就说,我现在的年龄,是我在36岁时你年龄的两倍,24*2 = 48.
如果想自己算出,可以设二人的年龄差为x,代入方程式算出,
36+x = 2*(36...

x=12
36+12=48

同意离开的积分的回答!
“twice“指的是大两倍,也就是说the other man的年龄(36岁)是a man当时年龄(X)的3倍,即36=3X,X=12,也就是说二人年龄相差12岁。a man现在36岁,那么the other man就是36+12=48岁。
