Answer: Option B

Solution(By Examveda Team)

According to the question,

Cost Price	:	Marked Price
(100 - Discount)	:	(100 + Profit)
100 - 15	:	100 + 19
85	:	119
34 units more

$$\eqalign{ & {\text{Raised}}\% = \frac{{34}}{{85}} \times 100 \cr & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, = 40\% \cr} $$
