Ese is 23 years old and her younger sister is 19 years old . What was the sum of their age 13 years ago

Answer 1

The sum of their ages 13 years ago would be:

23 - 13 = 10 years old for Ese
19 - 13 = 6 years old for her younger sister

So, the sum of their ages 13 years ago would be 10 + 6 = 16 years old.
