  1. I would recommend creating some equations.

    So... represent one of the people's ages with x and another person's with why and convert the statements of twice and the sum of their ages to different mathematical operations like multiplication or addition.

    So Kristen start with Kristen being Y and Ben being X and see what equations you get. Once you have two equations you can solve for your two unknowns x and y.
