Answer:
25%
Step-by-step explanation:
Step 1: Find the sale price
First, we have to find the price it was sold for.
[tex]\longmapsto[/tex] 5/4 of 800 = 5/4 * 800
[tex]\frac54 * 800 = \\\\\frac{4000}{4} = 1000\\\\[/tex]
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
[tex]\frac{1000}{800} = \frac54 = 1.25 = 125percent[/tex]
The cost of the article is 100% or 1
[tex]1.25 - 1 = 0.25 - or- 25percent[/tex]
25%
