Allowing 20 % discount on the marked price of an article and levying 15 % VAT. a buyer has to pay Rs 9.200 for the article. Find
nata0808 [166]

Answer:

here I'm confused that whether the selling price is Rs.9,200 or Rs.9.200

any ways you can take the help of below procedure

Step-by-step explanation:

here,

let marked price be X

discount(d)=20%

VAT=15%

SP with VAT= 9200

now,

SP without VAT= SP - VAT of SP

= 9200-15/100 ×9200

= 9200- 1380

=Rs. 1380

again,

SP= MP - D of MP

or,7820= x- 20/100 × x

or, 7820× 100 = 100x- 20x

or,782000=80x

or, 782000/80=X

or, X= 9775.

hence MP is Rs 9775

Which of the following points represents the center of a circle whose equation is (X - 5)2 + (y-4)2 = 25?
Ivan

The correct answer is option D. The coordinates of the centre for the given equation of a circle is (5,4).

The complete question is as below:-

Which of the following points represents the centre of a circle whose

equation is (X - 5)2 + (y-4)2 = 25?

A. (-5,-4)

B. (5,-4)

C. (-5,4)

D. (5,4)

<h3>What is a circle?</h3>

The circle is defined as the locus of the point traces around a fixed point called the centre and is equidistant from the out trace.

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r the radius

(x - 5)² + (y - 4)² = 25 ← is in standard form

We can see that the centre of the circle is (5,4) by comparing the equation with the standard form.

Therefore the correct answer is option D. The coordinates of the centre for the given equation of a circle is (5,4).
