A dealer lists his goods at 20% above cost price and allows a discount of 10%. His gain per cent is

Let CP will be Rs.100


Marked Price = Rs.120


10% Discount on Marked Price = 10% of Rs.120


= Rs.12


So, SP = 120 -12


= Rs.108


Gain = SP – CP


= 108 – 100


= Rs.8



= (8 × 100) / 100


= 8%
