Marks: +1, -0

A merchant marked the price of an article by increasing its production cost by 40%. Now he allows 20% discount and gets a profit of Rs. 48 after selling it. The production cost is

Rs. 320
Rs. 360
Rs. 400
Rs. 440

Validate

Solution:

(3) Let the production cost of article be Rs. x.
Effective percentage

= (x+y+ {x y}/{100} ) \%

= (40-20- {40 × 20}/{100} ) \%

=(20-8) \%=12 \%

According to the question,

12% \;\of\; x = 48

⇒{12 x}/{100}=48

⇒ x= {48× 100}/{12}= {Rs} .400
