Question

If the cost price of 20 articles is equal to the selling price of 25 articles, what is the % profit or loss made by the merchant?

Answer 1

Let the SP of 1 article = x
Then SP of 25 articles = 25x
ATQ,
CP of 20 articles = 25x
CP of 1 article = 25x/20 = 5x/4

comparing x and 5x/4 we find 5x/4> x => CP is more than SP
=> loss

Answer 2

Let the price be x....
so for 20 it becomes 20x

now ur sayin that sp of 25 is sam to tht of 20 cp
let sp be y

25y=20x

it shows y = 4/5x


or u can say 80% of x
