Price elasticity of demand class 11 microeconomics | meaning, formula with example

In this video, I discussed About the price elasticity of demand with formula derivation and example

[Jai_Shree_Ram]

Sir there is also a negative sign in the formula due to the negative relationship between price and demand and to deduct that negative sign ...in this question(-2) it will deduct from the negative sign which we use in formula so the elasticity will be only 1.25 🙃

Explain demand curve. A demand curve is given by
QD = 500 - 2PX
a. What is the total revenue function?
b. The marginal revenue function is MR = 250 – Q. Graph the total revenue function, the demand curve, and the marginal revenue function.
c. At what price is revenue maximized, and what is revenue at that point?
d. Identify the elastic and inelastic regions of the demand curve.

At a price of ` 5 per unit of a commodity A, total
