There are three people in Tom’s family.Their total age is 88.Mom is three times as old as Tom.Dad is four years older than Mom.How old is Tom?
选项
答案
Tom is twelve years old.
解析
汤姆家人总年龄是88。妈妈的年龄是汤姆的三倍。爸爸比妈妈大四岁。汤姆多少岁?根据题意可设汤姆X岁,题目中提到妈妈的年龄是汤姆的三倍,则妈妈的年龄为3X;爸爸比妈妈大四岁,则爸爸的年龄为3X +4;汤姆家人总年龄是88,则可列方程式X+3X +3X +4=88解方程可得X=12,即汤姆12岁。
