Work done between any two points in a electrostatic field only depends on the potentials of the two points. In your question work has been done between the same two points in either directions. The ratio will be 1:1
W = Potential difference / charge of the particle.
WAB = | VB - VA | / q
WBA = |VA - VB | / q
Dividing one by two.
WAB / WBA = | VB - VA | / |VA - VB | = 1
