Expert Answer:

No this case is not possible.
For any machine its efficiency is defined as
 
Efficiency = fraction numerator M e c h a n i c a l space a d v a n t a g e over denominator v e l o c i t y space r a t i o end fraction cross times 100
And its already been known no machine is 100 percent efficient.
So velocity ratio will always be greater than mechanical advantage.
