Correct Answer

Explanation

Sara's age now = 5x
Vaishali's age now = 3x
The ratio of Sara's age four years ago to Vaishali's age in the future was 1:1
Substituting the values:
(5x - 4) / (3x + 4) = 1/1

Solving the equation:
x = 4

This means that Sara is currently 20 years old and Vaishali is currently 12 years old. The ratio of Sara's age four years from now to Vaishali's age four years ago is 3:1.
