An article bought for rs. 800 is sold for 5/4 of the cost price. Find the profit percentage.

25%

Step-by-step explanation:

Step 1: Find the sale price

First, we have to find the price it was sold for.

5/4 of 800 = 5/4 * 800

The article was sold for rs. 1000

Step 2: Finding the percentage

To find the percentage, we have to divide the sale price over the cost of the article

The cost of the article is 100% or 1

25%

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

answer: 0.26
