Holmes and Watson had apprehended three people on suspicion of shop lifting. The three, a man, a woman and a boy, were interviewed by inspector Lestrade at Scotland Yard. During the interview it became clear that the man was three times as old as the boy and twice as old as the woman. The ages of all three added together is 88 years.
How old is each?
选项
答案
The man is 48 years old,the woman is 24 years old and the boy is 16 years old
解析
(本题可以设方程解答。设man的年龄是x,则女人的年龄是x/2,男孩的年龄是x/3,又因为他们的年龄之和是88岁,故x+x/2+x/3=88,解得x=48,即可得出其他两人的年龄。)
