Answer:
[tex]profit \: percent = \frac{sp - cp}{cp} \times 100 \: percent[/tex]
where,
SP=Selling price
CP=Cost price
Given,
Selling price(SP)= 1000
Cost price(CP)=800
Now,
[tex]profit \: percent = \frac{sp - cp}{cp} \times 100 \: percent \\ = \frac{1000 - 800}{800} \times 100 \\ = \frac{200}{800} \times 100 \\ = 25 \: percent[/tex]
Hope this helps...
Good luck on your assignment..
