Question

The selling price of 15 articles is equal to the
cost price of 12 ancies. Find the gain or loss
as percent
​

Answer 1

Answer:

gain%=25%

Step-by-step explanation:

selling price of 15 articles =x

selling price of 1 article=x/15

cost price of 12 articles =x

cost price of 1 article =x/12

as cp(x/15)<sp(x/12)

gain =sp -cp

=x/12 *x/15

=5x-4x/60

=x/60

gain%=x/60*15/x*100

=25%

Answer 2

Answer:

Step-by-step explanation:

Let the Sp of an article be Rs 1

Therefore, Sp of 15 articles = 15 Rs

Given : Sp of 15 articles =Cp of 12 articles

Therfore, Cp of 12 articles = Rs 15

Cp of 1 article=15/12=1.25 Rs

Therfore there is a loss as Cp>Sp

Loss= 1.25 Rs- 1.00 Rs

=0.25 Rs per article

Therefore, loss percent= 0.25/100*1.25

=1/320%
