urgent plz , i will mark the correct ans brainliest ​

Answer 1

Step-by-step explanation:

If he wants to cheat both by 10% then he will have to buy at 10% cheaper rate and sell for 10% more

suppose the original price is "x"

then he will buy for 10% less ftom seller

$90\% \: of \: x \: is \: \frac{90x}{100}$

now he will sell for 110% of the original price

$110\% \: of \: x \: is \: \frac{110x}{100}$

profit

$=\frac{110x - 90x}{100}$

$= \frac{20x}{100}$

this is 20% of the original price "x" so we can say he will make a profit of 20% oft he origibal price of the product
