The marked price of an article is 25% above the selling price and the cost price is 20% below the selling price. Find the rate o

MAXImum [283]

Step-by-step explanation:

The marked price of an article is 25% above the SP and the CP is 20% below the selling price. What is the rate of discount and the profit percentage?

Let C, M & S denote cost-price, marked-price & sell-price respectively of the article.

Hence from above data we get following relations,

M = (1 + 25/100)*S = 1.25*S ….. (1a)

C = (1 - 20/100)*S = 0.80*S ….. (1b)

From (1a) we get,

S = (100/125)*M = (4/5)*M

or S = (1 - 1/5)*M = (1 - 20/100)*M ….. (2a)

From (1b) we get,

S = (100/80)*C = (5/4)*M

or S = (1 + 1/4)*C = (1 + 25/100)*C ….. (2b)

Therefore

It is evident from (2a) that

the discount percentage = 20% [Ans]

It is evident from (2b) that

the profit percentage = 25% [Ans]

Canada has a population that is about 1/10 as large as the united states. If canadas population is about 32 million, about how m

Mice21 [21]

Call Canada's population $c$ , and call the U.S. population $u$ .

We see that $c=\frac{u}{10}$ . Substituting 32 million for c, we see that $32,000,000=\frac{u}{10}$ . Multiplying by ten, we see that $320,000,000=u$ . By using Algebra properly, we have ensured that the number of zeroes in our final answer is correct.
