Question

Cost of 20 articles is the same as selling price of x articles ,if profit is 25 per cent ,then value of x is

Answer 1

Answer:

Since we don’t know the cost of the article it is ok to assume a value initially.

Let the CP of each article =1 unit.

CP of 20 articles =20 units

SP of x articles=CP of 20 articles= 20 units

SP of 1 article = 20/x

using formula Profit%=((SP-CP)/CP)*100 for 1 article as profit% is a constant for each article.

25=(((20-x)/x)/1)*100 | 25x/100 = 20-x | x/4 = 20-x | 5x=80

solving we get x=16 units.
