Question

`Judith is 5 years younger than Trina and 5 years older than Gretchen. The average of their ages is 23. How old is each Woman?

Answer 1

Gretchen: 18

Judith: 23

Trina: 28

Explanation:

Do reverse math. to find the average you would normally add up each age and divide your answer by the amount of ages provided. but in this case we don't have enough information so you do it opposite.

23x3=69.

Trina is clearly the oldest and Gretchen is the youngest, leaving Judith in the middle.

Gretchen: 18

Judith: 23

Trina: 28

it takes some experimenting with numbers but this is correct because all three numbers add up to 69 and they are each 5 years apart.
