let CP of one article be = 10
CP of 10 articles = 100

SP of 8 articles = 100
SP of one article = 100/8 = 12.5

So the gain = (2.5/10)*100 = 25%.

the guest was me....sorry i forget to login always..

there is a shortcut to approach these type of problems too..
If the CP of x articles is equal to the selling price of y articles, then if y is less than x, the retailer makes a profit and the profit % is [(x-y)/y]*100.

And, if y is greater than x, then the retailer makes a loss and the loss % is [(y-x)/y]*100

Same method. Am surprised we chose the same number as article price.
