Source: Manhattan GMAT
Target question: How old is Carmen now?
Given: 3 years ago Jennifer was 22 years old
So, Jennifer's PRESENT age is
25
Statement 1: 10 years ago, Carmen was twice as old as Jennifer.
If Jennifer's PRESENT age is
25, then Jennifer's age 10 YEARS AGO was 15
This means Carmen's age 10 YEARS AGO was 30, which means
Carmen's PRESENT AGE is 40
Since we can answer the
target question with certainty, statement 1 is SUFFICIENT
Statement 2: 10 years from today, Carmen will be 15 years older than Jennifer.
This just tells us that Carmen is 15 years older than Jennifer
If Jennifer's PRESENT age is
25, then
Carmen's PRESENT AGE is 40
Since we can answer the
target question with certainty, statement 2 is SUFFICIENT
Answer: D
