A man sold a mobile phone for rupees 6251 and lost one upon 20 of cost price. Find the CP of mobile phone and his loss percent​.

                                                                                     

║⊕ANSWER⊕║

Selling price = 6251

Cost price = x

Cost price - Selling price  = 1/20 of cost price

x - 6251 = 1/20 x

x - 6251 = x/20

20(x- 6251) = x

20x - 125020 = x

20x - x = 125020

19x = 125020

x = 6580

⇒ Cost price of the mobile phone is Rs. 6580.

Loss = 6580 - 6251 = Rs.329

Percent = 329/6580  x 100 = 5%
