If Finn was 18 months old one year ago, how old was he, in months, x months ago?

A. x − 30

B. x − 12

C. 18 − x

D. 24 − x

E. 30 − x

Now Finn's age=18+12=30 months

So, x months ago his age was (30-x) months

Correct Answer E

Finn is 18+12=30 months today. Reducing Finn's age with x months would make him 30 minus x years old -> 30-x years old.
