Question

Question-2) if the cost price of 10 articles is equal to the selling price of 8 articles, Find the gain or loss per
cent.​

Answer 1

Answer:

let cp of each article be x

cp of 10 articles =10x

A/Q

cp of 10 articles=sp of 8 articles

10x=sp of 8 articles

But cp of 8 articles =8x

Here sp is greater than cp

there is profit

profit=sp-cp

=10x-8x=2x

profit%=profit/cp×100

=2x/8x×100=25%gain
