A Correct answer
Explanation

Let B's CP = x, then A's CP = 2x. Total CP = 3x. Both marked up 30%, so total MP = 1.3 × 3x = 3.9x. After Rs 99 discount, SP = 3.9x - 99. Profit is 19%, so SP = 1.19 × 3x = 3.57x. Equating: 3.9x - 99 = 3.57x, so 0.33x = 99, x = 300. A's CP = 2x = Rs 600. The cost price of article A is 600.
