Question

If the selling price of 4 articles is equal to the
cost price of 5 articles, find the gain or loss percent ?
kindly include steps too ​

Answer 1

Answer:

25% profit

Step-by-step explanation:

Profit and gain are same things, but I prefer using 'profit'.

SP (selling price)

CP (cost price)

SP of 4 articles = CP of 5 articles

Profit = SP of 4 articles - CP of 5 articles

          = SP of 4 articles - CP of 4 articles

          = CP of 5 articles - CP of 4 articles (as SP of 4 articles = CP of 5 articles)

          = CP of 1 article (x)

          = 1 × x

          = x

Profit% = $\frac{profit}{cp}$ × 100

Profit% = $\frac{x}{4x}$ × 100 (we always take the new value of CP, which in our case is 4)

Profit% =  25

Answer 2

Answer:

selling price =cost of five article

let the S.P.of 1 article=1.then SP of 5 articles=5

so, SP of 4 article=CP of 5 articles=18

CP>SP ,so gain =sp-cp=5-4=1

gain %=gain ×100/cp%=1×100/5%

100/5=50%

so your answer is 50...

hope this will help u!!
