Let × be the CP of the cellphone.
Market Price of the goods when goods is marked above 40% of CP
Market Price = × + (40x/100)
Discount Offered = 30%
Discounted Amount = 30% of 1.40x
Selling Price = Market Price – Discount
= 1.4 × – 0.42x
Since CP is more than SP, it is a case of Loss.
Loss = CP – SP
= × – 0.98x
