Age of Marge is 18 years

Age of Consuelo is 9 years

Solution:-

Let Age of Marge be m and age of Conauelo be c

Given that m = 2c

7 Years ago Age of Marge was m -7

So we can write as:-

m - 7 + c - 7 = 13

By plugging the value of m = 2c

We get:-

2c + c = 27

Therefore;Age of Consuelo is 9 years

m = 2c = 2 × 9 = 18

And Age of Marge is 18 years
