Question

the cost price of 20 articles is same as the selling price of 16 articles find the gain percent​

Answer 1

Answer:

Solution (Total 7)

let cp of 20 articles = rs x.

then c.p of 1 article = x/20

similarly sp of 16 articles is also rs x as mentioned.

then sp of 1 article = x/16

then loss % = [(x/16-x/20)/(x/20)]* 100=25%

Answer 2

gain%= (20-16) x 100/16

4x100/16 = loo/4=25%
