Options

A. `(1)/(9)` th of marked price
B. `(4)/(9)` th of marked price
C. `(5)/(9)` th of marked price
D. `(7)/(9)th` of marked price

Answer

C

Explanation

Let the CP = Rs. 100
= SP = Rs. 90
=MP`=90xx2= Rs. 180`
`(therefore` SP will be half of the MP as the discount is also equal to half the MP)
`=(CP)/(MP)=(100)/(180)=(5)/(9)`
`=CP=(5)/(9)` of MP
