Problem : Avinash bought a mobile phone for Rs 2000 and sold the same for Rs 1900. Find his loss percent.
Solution : Cost price of mobile phone = Rs 2000
Selling price of mobile phone = Rs 1900
Since selling price is less than cost price, so there is a loss.
Loss = Cost Price − Selling price
= 2000 − 1900
= Rs 100
Let x% be the loss suffered by Avinash. Then,
⇒
⇒x = 5
∴ Avinash suffered a loss of 5% in this transaction.
