Answer:
   ₹14000
Step-by-step explanation:
Let c represent the cost price, and m represent the marked price.
   c × (1 +40%) = m
   m × (1 -15%) - c = ₹1900
Using the first expression for m, the second equation becomes ...
   1.40c×0.85 -c = ₹1900
   0.19c = ₹1900
   c = ₹1900/0.19 = ₹10000
Then the marked price was ...
   m = 1.40c = 1.40×₹10000 = ₹14000
The marked price was ₹14000.
_____
The selling price was ₹11900.
