Calculate the marked price(original price)if after 20% discount, the price of an article.
Elina [12.6K]

Answer: An article was sold at a 20% discount, at Rs. 400. What was its marked price?

Let M denotes the required marked price of the given article.

Hence from above data we get following relation,

(1 - 20/100)*M = 400

or (4/5)*M = 400

or M = (5/4)*400 = 500 (Rs) [Ans]

If the area of a square with side x is equal to the area of a triangle with base x, then find the altitude of the triangle.
zhannawk [14.2K]

Answer:

h= 2x

Step-by-step explanation:

Given

Square

Side = x

Triangle

Base = x

Altitude = h

Required

Find h, if both shapes have the same area

The area of the square is:

Area = x * x

Area = x^2

The area of the triangle is:

Area = \frac{1}{2} * Base*Height

Area = \frac{1}{2} * x*h

Equate both areas

x^2 = \frac{1}{2} * x*h

Divide both sides by x

x = \frac{1}{2} *h

Multiply both sides by 2

2*x = \frac{1}{2} *h*2

2x = h

h= 2x
