Correct answer: C

Solution:

  • Let the cost price be x.

  • Selling at a 10% loss gives selling price = 0.9x.

  • If it was sold for Rs.140 more, the new selling price = 0.9x + 140.

  • This new selling price corresponds to a 4% gain, so 0.9x + 140 = 1.04x.

  • Solve the equation: 140 = 1.04x - 0.9x = 0.14x, so x = 140 / 0.14 = 1000.

  • Therefore the cost price is Rs. 1000. Quick check: 10% loss → SP = Rs.900; adding Rs.140 gives Rs.1040, which is 4% above Rs.1000.
