Question

A man bought an article on 30% discount and sold it at 40% more than the marked price.
Find the profit made by him.​

Answer 1

If the man bought an article on 30% discount & sold at 40% more than M.P. then the profit is 100%.

Step-by-step explanation:

Step 1:

Let the marked price (M.P.) of the article be “Rs. 100”  

Discount = 30%

It is given that the man had bought the article on the discounted rate of 30%, therefore,

The C.P. of the article = Rs. 100 – [30%of 100] = Rs. 70

Step 2:

Also given, that the article was sold at a rate of 40% more than the marked price  

So, S.P. of the article = Rs. 100 + [40% of 100] = Rs. 140

Step 3:

Thus,  

The profit made by him will be,

= [(C.P. – S.P.) / C.P.] * 100

= [(140 - 70)/70] * 100

= 100%

Answer 2

Answer:

100%

Step-by-step explanation:

Let marked price of article=Rs 100

Discount=30 %

Discount=$\frac{30}{100}\times 100=$ Rs 30

Cost price=Marked price-Discount

Cost price=100-30=Rs 70

Selling price=$100+\frac{40}{100}\times 100=$ Rs 140

Profit=S.P-C.P=140-70=Rs 70

Profit %=$\frac{profit}{C.P}\times 100=\frac{70}{70}\times 100=$ 100%

Hence, the profit made by him =100%
