Question

If the cost price of 8 articles is equal to the selling price of 10 articles, find the loss per cent.​

Answer 1

Answer:

cost price of one article is Rs x

cost price of 8 article is Rs 8x

selling price of 10 articles is Rs 8x

selling price of one article is Rs 8x/10

loss=Rs (x-8x/10)=Rs 2x/10=Rs x/5

loss percent=x/5.100.1/x %=100/5%=20%
