A trader marks his goods at 30% above cost price and allows a discount of 10%. What is his gain per cent?


Let CP will be Rs.100


Marked Price = Rs.130


10% Discount on Marked Price = 10% of Rs.130


= Rs.13


So, SP = 130 -13


= Rs.117


Gain = SP – CP


= 117 – 100


= Rs.17



= (17 × 100) / 100


= 17%
