Question

If you're three years older than twice as old as your twelve year old sister, how old will you be when you're less than twice as old as her?

Answer 1

My current age =2*12+3=27
Let after x years I will be less than twice as old as her
So according to question
27+x <2(12+x)
27+x<24+2x
27-24<2x-x
3<x
As x>3
So my age should be >27+x
>27+3
>30
so my age should be 31 years.
