Jane started baby-sitting when she was 18 years old. Whenever she baby-sat
for a child, that child was no more than half her age at the time. Jane is currently
32 years old, and she stopped baby-sitting 10 years ago. What is the
current age of the oldest person for whom Jane could have baby-sat?

OA 23

Jane stopped baby sitting at the age of 22, so the baby she looked after at time must be 11.
and now the baby will be [spoiler]11+10 = 22yrs old[/spoiler]

At age 18, the baby is 9yrs.
At age 32, the baby would be [spoiler]9+14=23yrs.[/spoiler]

Correct me if I am wrong.
