Question

if the selling price of 10 articles is cost price of 11 articles , find the gain or loss percentage

Answer 1

Let the cost price of one article is Rs. 100
Then cost price of 11 article is Rs. 100 X 11 = Rs. 1100

According to question
Selling price of 10 article = Cost price of 11 article(Rs 1100)
Selling price of 1 article = Rs. 1100/10 = Rs 110

Gain % = 110 -100 = 10%

SHORT TRICK ={ (No. of cost article/No. of selling article)X 100 } - 100
If the answer is positive then there is gain and if answer is negative then there is loss


In this question Ans {(11/10) X 100} -100 = 110 -100
