A dealer marks his goods at 35% above the cost price and allows a discount of 20% on the marked price. Find his gain or loss per cent.
Answer :
Let × be the CP of the goods.
Market Price of the goods when goods is marked above 35% of CP
Market Price = × + (35x/100)
= 135x/100
Discount Offered = 20%
Discounted Amount = 20% of 135x/100
= 27x/100
Selling Price = Market Price – Discount
= (135x/100) – (27x/100)
=108x/100
=1.08x
Since SP is more than CP, it is a case of Gain.
Gain = SP – CP
= 1.08x– x
= 0.08x
= 
= 8%
