A Correct answer
Explanation

Brand A removed: 12% of 600 = 72. Brand B removed: 25% of 1200 = 300. Total removed = 72 + 300 = 372. Total pens = 600 + 1200 = 1800. Percentage removed = (372 / 1800) * 100 = 20.66%, which is approximately 21%.

AI explanation

The number of brand A pens removed is 12% of 600, which equals 72 pens. The number of brand B pens removed is 25% of 1200, which equals 300 pens. The total pens removed is 372 out of the initial total of 1800 pens. The percentage removed is 372 divided by 1800 and multiplied by 100, resulting in approximately 21%.
