Question

if the selling price of 50 articles is equal to the cost price of 40 articles then loss or gain percent will be

Answer 1

let CP of 1 article = 10
CP OF 40 articles = 400

CP of 40 articles = SP of 50 articles
400. = SP of 50 articles
8. = SP of 1 article

As CP is greater than SP, loss occurs
loss = CP- SP
= 10-8 = 2
loss%= loss/CP * 100
= 2/10 *100
= 20%

Answer 2

Answer:

SELLING PRICE 50 ARTICLES = COST PRICE 40 ARTICLES

SP = CP + PROFIT

50 = 40 + PROFIT

PROFIT = 10

PROFIT PERCENTAGE = (P/CP) * 100

         (10/40) *100

     = 25 %
