Question: A shopkeeper marks his goods 30% above his cost price but allows a discount of 10% at the time of sale. His gain is =?

Solution:

Let the cost price be Tk.100

Then the markup price which is 30% above the cost price,

Mark price = (100 + 30% of 100) = Tk. 130

The shopkeeper gives a discount of 10% on mark up price, then the

Selling Price = (130 - 10% of 130) = Tk. 117

Gain = 117 - 100 = Tk. 17

∴ His gain in percentage is = (17 × 100)/100
= 17%
