If we move from 8 to 6, the elasticity of demand is?

A. -1.25
B. 0.62
C. 1.25
D. 1

Correct Answer: Option C

C. 1.25

Explanation
The elasticity of demand is calculated using:

ρd = % Δ in P
% Δ in Q

NOTE: Elasticity of demand is always positive. Therefore, the negative sign is ignored or In extra negative sign is introduced to make it positive. So the answer is 1.25
