Question

find the loss or gain percentage, if the cp of 10 articles, all are of same kind,is equal to the sp of eight articles.

Answer 1

Answer:

Given: 10 X CP = 8 X SP (from  the question write like this)

Cross multiplying we get : SP/CP = 10/8

Since Numerator SP is more than denominator CP, we conclude that the transaction is profitable.

Hence profit = SP-CP which is 10-8= 2

Profit Percentage = Profit X 100/CP

Ie. 2X100/8 = 25%

Ans: 25%

Step-by-step explanation:

Answer 2

Answer:

25%

Step-by-step explanation:

let the cp be ₹ 80

Cp of 1 article = 80 / 10 = ₹ 8

SP of 1 article = ₹ 10

gain = sp - cp = ₹ 10 - ₹ 8 = ₹ 2

gain % = 2× 100 / 8 = 25 %
