The Correct Option is B
Solution and Explanation
Let the price of good mangoes be \( x \) per kg. Therefore, the price of medium quality mangoes is \( \frac{x}{2} \) per kg. The shopkeeper buys:
- 80 kg of good mangoes at \( x \) per kg, total cost = \( 80x \).
- 40 kg of medium quality mangoes at \( \frac{x}{2} \) per kg, total cost = \( 40 \times \frac{x}{2} = 20x \).
Total cost price for the shopkeeper = \( 80x + 20x = 100x \).
The selling price per kg is 10% less than the price of good mangoes, so the selling price per kg = \( x - \frac{10}{100}x = 0.9x \).
- The shopkeeper sells 80 kg of good mangoes + 40 kg of medium quality mangoes = 120 kg at \( 0.9x \) per kg.
- Total selling price = \( 120 \times 0.9x = 108x \).
Profit = Selling Price - Cost Price = \( 108x - 100x = 8x \).
Profit Percentage = \( \frac{\text{Profit}}{\text{Cost Price}} \times 100 = \frac{8x}{100x} \times 100 = 8\% \).
Therefore, the overall profit is 8%.

- The passage given below is followed by four summaries. Choose the option that best captures the essence of the passage.
In the dynamic realm of creativity, artists often find themselves at the crossroads between drawing inspiration from diverse cultures and inadvertently crossing into the territory of cultural appropriation. Inspiration is the lifeblood of creativity, driving artists to create works that resonate across borders. In a globalized era of the modern world, artists draw from a vast array of cultural influences. When approached respectfully, inspiration becomes a bridge, fostering understanding and appreciation of cultural diversity. However, the line between inspiration and cultural appropriation can be thin and easily blurred.
Cultural appropriation occurs when elements from a particular culture are borrowed without proper understanding, respect, or acknowledgment. This leads to the commodification of sacred symbols, the reinforcement of stereotypes, and the erasure of the cultural context from which these elements originated. It is essential to recognize that the impact of cultural appropriation extends beyond the realm of artistic expression, influencing societal perceptions and perpetuating power imbalances.- CAT - 2025
