The profit margin on a sofa set is 100%. If the cost price of the sofa set falls by 20% then what will be the new profit margin (in %)?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. 150

Understanding

Application

Profit margin = 100%

Suppose CP = X

So,

SP = 2X

Cost price of the sofa set falls by 20%

So,

New CP = 0.8X

Hence,

Profit margin = [(2X – 0.8X)/0.8X] × 100

= 150%
