A. 44%✓ Correct Answer
B. 39%
C. 25%

💡 Solution & Explanation
Take the price as 100. After 30% off it is 70. The second discount of 20% is on 70, which is 14, leaving 56. The total reduction is 44, so the single discount is 44%. Shortcut: a + b − ab/100 = 30 + 20 − 6 = 44%. Simply adding gives 50%, which is too high.
