CAT 2021 Quant Question [Slot 1] with Solution 20

Option: 2
Solution:
Let the selling price of the Large and Small boxes of chocolates be Rs.200 and Rs.100 respectively. Let us consider that the Large box has \(L\) grams of chocolate while the Small box has \(S\) grams of chocolate.
The relation between the selling price per gram of chocolate can be represented as: \(\frac{{200}}{L} = 0.88 \times \;\frac{{100}}{S}\)
On solving we obtain the ratio of the amount of chocolate in each box as: \(\frac{L}{S} = \frac{{25}}{{11}}\)
The percentage by which the weight of chocolate in the large box exceeds that in the small box = \(\left( {\frac{{25}}{{11}} - 1} \right) \times \;100 \approx \;127\% \)
