What percentage of the selling price of an article would be 40% of the cost of that article?

Given:

Marked Price(MP) = 40% more than Cost Price(CP)

Discount = 50%

Concept:

Discount always done on Marked Price

Selling Price(S.P) = Marked Price - Discount

Calculation:

Let the Cost price be Rs. 100

⇒ MP = 100(100 + 40)/100

⇒ Rs. 140 

⇒ Discount = 50% of MP

⇒ (50/100) × 140 = 70

Selling Price(S.P) = Marked Price - Discount

⇒ SP = 140 – 70 = 70

Now,

The Required percentage = (70/100) × 100 = 70%.

Let the cost price be 100

Selling price = Marked price 40% the cost price of Discount %

⇒ 100 × (140/100) × 50/100

⇒ S.P = Rs. 70

According to the question,

⇒ (70/100)× 100 

⇒ 70%

∴ The required answer is 70%.
