Given∶ Loss = 6% Formula used∶ Selling price = cost price – loss Selling price = cost price + profit Calculation∶ Let the cost price is Rs. x Selling price =x–6% of x ⇒ 94x/100 New selling price =x+15% of x ⇒(94x/100)+15750=x+15% of x ⇒(94x/100)–(115x/100)=−15750 ⇒21x/100=15750 ⇒x=Rs.75,000 ∴ The cost price is Rs. 75,000.
