Answer 2

Step-by-step explanation:

Cp of 20 article is equal to the sp of 10 articles

let cp of 1 article be $100

cp of 20 article 100x20=2000

so cp of 20 article is 2000

so given sp of 10 articles is 2000

so sp of 1 article is 2000/10 =200

so gain percent formulae = sp-cp

=200-100=100

gain =$100

gain percent formulae = gain/ cp x100percent
