Question

find the loss or gain as percent ,if the cp of 10 article ,allof the same kind equal to selling price of 8 article.

Answer 1

Let us calculate the cost price of 1 article

let 10 articles cost x.

1 article will cost x/10

Selling price let value of 1 article sold be y.

So according to question

x=8y

y=x/8

so each article costs Rs.x/8 while selling.

Now profit=sp-cp/cp*100

(x/8)-(x/10)/(x/10)  *100

take lcm we get (x/40)/(x/10)  *100

25% gain

Answer 2

Answer:

Step-by-step explanation:

sp of 8 articles = cp of 10 articles

if gain sp > cp

10-8 = 2

hence Gain = 2/8*100

=25%
