A. 19%

B. 78.4%

C. 22%

D. 19.6%

Answer: Option D

Solution(By Examveda Team)

Initial CP = 400
After marking 30% up, marked price = 520
He allowed a discount of 8%, discount = 41.6
Selling price = 520 - 41.6 = 478.4
$$\eqalign{ & \% {\text{profit}} = \frac{{\left( {478.4 - 400} \right)}}{{400}} \times 100 \cr & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, = \frac{{78.4 \times 100}}{{400}} \cr & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, = \frac{{7840}}{{400}} \cr & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, = 19.6\% \cr} $$
