Well, if you're three years older than your sister now, you must be feeling pretty ancient. In 20 years, your sister will be twice as old as you are now, which means she'll be catching up to your current age. So, if you're feeling old now, just wait until your sister starts lapping you in the age race.

If you mean "now you are 100 years old", then, my sister is now 98 years old, since she was 2 when I was 4.
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.
When you were 4 she was 2. You were two years older than she was. So if you are now 100 she is 98
her sister is approximately 5 years, and 3 months old
She doesn't have a half sister.
