Question

the cost price of 24 articles is the selling price of 15 articles ​

Answer 1

Answer:

So selling price of 15 articles= 24*x=24x. Cost price of 15 articles=15x. Gain= 24x-15x= 9x. So gain%= gain/CP ×100.

Answer 2

Answer:

Lost c. p of one article be x.

so c. p of 15 article will be 15*x= 15x

c. p of 24 articles = s. p of 15 articles.

so s. p of 15 articles = 24*x=24x

c. p of 15 article =15x

gain=24x-15x = 9x

so gain% = gain/c.p*100

= 9x/15x*100

=3*20=60%
