Mechanical advantage is ratio of load lifted to effort applied to it. 
 
M. A. space equals space fraction numerator L o a d over denominator E f f o r t end fraction O R M. A equals space fraction numerator E f f o r t space a r m over denominator L o a d space a r m space end fraction
 
Here, effort arm (handles of scissor) = 10 cm 
and load arm (blades of scissor) = 2 cm
 
M. A space equals space fraction numerator space 10 space c m over denominator 5 space c m space end fraction equals space 2
Thus, mechanical advantage of the scissor = 2
