On selling an article for Rs 329, a dealer lost 6%. The cost price of the article is

On selling an article for $ 329.

A dealer lost 6% of the cost price.

So , Selling price = 329

And , lost = 6%

Cost price = ?

According to the question:

Loss = 6=6 × 329/100329/100

1974/1001974/100

19.7419.74

So , the loss of the dealer is = $19.74

We have to find cost price of article by using formula :

Cost price = selling price + loss

329 + 19.74329+19.74

348.74348.74

So , the cost price of the article is $348.74

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
