I met a girl some days before when I was walking through a park with my children. My children and she became friends and started playing together. I decided to talk to her and during the conversation I asked her age. The smart girl replied, Two days back I was ten years old, and next year I shall be 13. If you know what is taday, you will be able to figure out my age!!!

It took some time for me to calculate her age. What about you?





Solution
The date on which I met the girl was 1st January 2007. The girl's birthday was on 31st December 1995. So The girl was 11 years old on the date I met her.
