Question

6. A dealer marked his goods 35% above cost price and allowed a discount of 20% on the marked
price. Find his gain or loss per cent.
​

Answer 1

Let us consider the CP of goods as x

Market price of the goods when goods marked above the 35% CP is

Market price = x + (35x/100) = 135x/100

So the Discount = 20%

Discount amount = 20% of 135x/100 = 27x/100

∴ The SP = Market price – Discount

= (135x/100) – (27x/100) = 108x/100 = 1.08x

Since, SP is more than CP it’s a gain

We know that, Gain = SP – CP

= 1.08x – x = 0.08x

∴ Gain % = (Gain × 100)/ CP

= (0.08x × 100)/ x

= 8%
