  1. Answer:

    25%

    Step-by-step explanation:

    price of twenty articles = x;

    price of one article = x/20// cp of 1 article

    ATQ:

    price of sixteen article  x;

    price of one article =  x/16;

    gain on 1 article = 20x-16x/320=x/80;

    gain % = gain/cp of 1 article*100;

    = 25%
