Hence, you would be missing 1% of which half would be above age 100 and half would be below (73-27) age 46.
If when you were 2 years old your sister was half of your age, you would have been 2 and she would have been 1. So she is one year younger than you. Thus now you are 100 she will be one year younger and aged 99.
