Solution
Let the present ages of Gloria and Sara be G and S respectively
it is given that $\frac{G}{S}$ = $\frac{4}{7}$..............(1)
Now two years back Gloria's age would be G-2 and Sara's age would be S - 2 and it is given that $\frac{G-2}{S-2}$ = $\frac{1}{2}$.............(2)
Solving 2 equations will give S = 14 years and so three years hence age of Sara will be 14 + 3 = 17 years
