Answer 2

Step-by-step explanation:

let cp of 9 article be x

let cp of 9 article be xcp of 1 article = x/9

let cp of 9 article be xcp of 1 article = x/9sp of 5 article = x

let cp of 9 article be xcp of 1 article = x/9sp of 5 article = xsp of 1 article = x/5

let cp of 9 article be xcp of 1 article = x/9sp of 5 article = xsp of 1 article = x/5profit = sp - cp

$\frac{x}{5} - \frac{x}{9} \\ = \frac{9x - 5x}{45} \\ = \frac{4x}{45}$

gain percent=

$\frac{p}{cp} \times 100 \\ = \frac{ \frac{4x}{45} }{ \frac{x}{9} } \times 100 \\ = \frac{4x}{45} \times \frac{9}{x} \times 100$

= 80%
