the Marked price of an article is 25% above its cost pricewhen ut is sold at a discount of 15%,there is a gain of rs 200 find the cost price and marked price of an article .​

man marks the price of his articles at 25% more than C..P

Let cost price (CP) of article be = ₹100

25% of 100 = ₹25

Thus he marks it's price = ₹100 + ₹25 = ₹125

The man then allows 15 percent discount on marked price

15% discount on ₹125

= 15/100 × 125

= 75/4

= ₹18.75

Discount is ₹18.75

Selling price of article = ₹125 –₹18.75

Selling Price of article = ₹106.25

Profit = Sale price - Cost price

Profit = ₹106.25 – ₹100 = ₹6.25

Profit % = Profit/Cost price × 100

Profit % = ₹6.25/₹100 × 100

Profit % = 6.25%

Answer : his percentage profit on sale of articles is 6.25%

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
