A trader marks his articles 20% more than the cost price. If he allows 20% discount, then find his gain or loss percent?

A. No profit No loss
B. 4% profit
C. 2% loss
D. 2% profit
E. None of these
Explanation:
Let CP of an article = RS. 100
MP= Rs. 120
Discount = 20%
SP = M[(100 – d%)/100] = 120(80/100) = Rs. 96
Clearly, the trader gets 4% loss.
