Q.

(Where Ed = elasticity of demand, Q = Quantity, P = Price and Δ = represents change)
-
A
Ed = ΔQ/Q×ΔP/P
-
B
Ed = ΔQ/Q÷ΔP/P
-
C
Ed = ΔP/ΔQ×Q/Y
-
D
Ed= ΔP/P÷ΔQ/Q
(Where Ed = elasticity of demand, Q = Quantity, P = Price and Δ = represents change)
Ed = ΔQ/Q×ΔP/P
Ed = ΔQ/Q÷ΔP/P
Ed = ΔP/ΔQ×Q/Y
Ed= ΔP/P÷ΔQ/Q
