A Correct answer
Explanation

Let CP = x for each. First SP = 1.15x. Second SP = 1.15x + 5200. Total CP = 2x, total SP = 2.3x + 5200. Net profit = 20%, so 2.3x + 5200 = 1.2(2x) = 2.4x. This gives 5200 = 0.1x, x = 52000. Check: profit on first = 7800, profit on second = 13000, total = 20800 which is 20% of 104000.
