Question

the cost price of 16 article is equal to the selling price of 12 articles find the gain percent​

Answer 1

let cp of 1 article = 1 rupee

cp of 16 articles = 16rs = sp of 12 articles

sp of 1 article = 16/12 = 4/3 = 1 1/3

gain% = sp-cp/ cp ×100%

= ⅓ / 1 ×100

= 33 1/3%

alternate way:

treat cp articles as sp and sp articles as cp

so cp = 12 and sp =16

gain % = 16-12/12 ×100= 1/3×100%

= 33 1/3%

Answer 2

Answer:

33 1/3 %

is the correct answer
