B Correct answer
Explanation

Let chargers = 14k and memory cards = 20k. Total = 34k. Mobile phones = 1.8 * 34k = 61.2k. Percent more on mobile phones than chargers = ((61.2k - 14k) / 14k) * 100 = (47.2 / 14) * 100 = 337.14%.

AI explanation

Let the total money spent on memory cards and chargers be x; the amount spent on mobile phones is 80% more, making it 1.8x, so the total bill of Rs. 23,800 equals x plus 1.8x, which gives x as 8500. The mobile phone cost is 1.8 multiplied by 8500, equaling Rs. 15,300. Within the combined x amount, the ratio for chargers to memory cards is 14 : 20, meaning chargers account for 14 out of 34 parts; thus, the charger cost is 14/34 of 8500, which is Rs. 3,500. The amount spent more on mobile phones than chargers is 15300 minus 3500, which is Rs. 11,800; calculating this as a percentage of the charger cost gives (11800 / 3500) multiplied by 100, resulting in 337.14%.
