Please mark the answer as "The Brainliest answer" if you like it

Step-by-step explanation:

Market Price = M

Discount = (15/100)*M = 0.15M

Selling Price = M -0.15M = 0.85M

Cost Price = C

Profit = (19/100)*C = 0.19 C

Selling Price = C + 0.19C = 1.19 C

1.19 C = 0.85 M

M = 1.4 C

1.4C - C = 0.4C

(0.4C/C)*100 = 40%
