jack 的年龄是 bill 的两倍,bill 比 ben 小八岁,ben 比 ted 小四岁,ted 年龄是 jack 的一倍.问 bill 多大?
答案:4岁.
bill=1/2 jack
ben=bill+8=1/2 jack +8
ted=ben+4=1/2 jack +8+4=2 jack,3/2 jack=12,jack=8,bill=8/2=4
Jack的年龄是Bill年龄的两倍,Bill比Ben小8岁,Ben比Ted小4岁,Ted的年龄和 Jack一样大
Bill is 12 years old.
Jack的年龄是Bill的2倍,Bill比Ben小8岁,Ben比Ted小4岁,Ted的年龄是Jack的一半.Bill多大?
