Find profit or loss percent if cp of 20 articles is equal to sp of 10 articles.

Answer»

Let the CP of one articles be ₹x .

SP of 10 articles = CP of 20 articles
= ₹(20X) .



CP of 10 articles = ₹(10×x) = ₹10x .
Since SP>CP , hence there is a PROFIT .

Profit = SP - CP = ₹20x - ₹10x = ₹10x .


profit \: \% \:  =  \frac{profit}{cp}   \times 100
profit \: \% =  \frac{10x}{10x}  \times 100 = 100\%
