In what year did Lynn turn 21?

• A. 2020
• B. 2019
• C. 2021
• D. 2022

Answer: (A)

If someone turns 21 in a given year, that year is when their age becomes 21. You can think of it as birth year plus 21 equals the year they turn 21. Here, the year Lynn turns 21 is 2020, so her birth year would be 2020 minus 21, which is 1999. That confirms the turning year as 2020. If it were a different year, the birth year would shift accordingly (for example, turning 21 in 2019 would imply a birth year of 1998).
