D m (d o the following question with full detail and also if needed post the diagram)

Since a detailed explanation is needed, I will explain each option in a separate comment. The confusion in this question arises out of the fact that there are multiple ways to cal...

Coming to option (A), again we make use of the geometric method. Elasticity across a linear demand curve is calculated by taking ratio of lower segment to upper segment, and this y...

nice explanation

Option (C) is also correct because that's what the formula needs. Price elasticity of demand pertains to how much does the quantity demanded change for a unit change in price. This...

Option (D) is correct and it also makes use of the geometric method again. Please refer to my first comment for a detailed explanation, and this attached figure as well.

Let me know if the concept is still not very clear.
