The area VWX

The area XTUV
C
\(\frac {XW} {XT}\)
D
\(\frac {TU} {UV}\)
Ask EduPadi AI for a detailed answer
Correct Option: A
From the diagram, the consumer budgeted TUX while the market price is TUVW, therefore, consumer surplus is TUX - TUVW which is equal to VWX.
Consumer surplus is the difference between what a consumer budgeted to have a commodity and the actual amount he paid to have the commodity.
