Show answer & explanation

Correct answer: C

Explanation

The correct answer is Option 3 i.e. 300.

MP = Rs. 550

Discount = 40%

SP=MP×100−D100SP = {MP \times {{100 - D} \over 100}}

SP=550×100−40100SP = {550 \times {{100 - 40} \over 100}}

⇒ SP=550×60100SP = {550 \times {60 \over 100}} 

⇒ SP = 330

SP is 10% more than the CP.

SP = 110% of CP

⇒ 330 = 110100110 \over 100 × CP

⇒ CP = 300
