Show Solution

The Correct Option is B

Solution and Explanation

The person has no toffees remaining after distributing to the fifth student.

Each student receives one more than half the number of toffees available at that point.

For this problem, working backward is the most efficient approach. If the person had not given an additional toffee, they would have retained that single toffee.

This implies the person had \(2\) toffees at that stage. In the preceding stage (the 4th stage), they must have had \((2+1)×2\), which equals \(6\) toffees. In the 3rd stage, they should have had \((6+1)×2\), totaling \(14\) toffees.

In the 2nd stage, they should have had \((14+1)×2\), resulting in \(30\) toffees.

In the 1st stage, they should have had \((30+1)×2\), which amounts to \(62\) toffees.

Therefore, the initial number of toffees was \(62\).

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.
