The Correct Option is B
Solution and Explanation
Let the numbers be $2x$, $3x$, and $\frac{9x}{5}$. Their sum is 136: $2x + 3x + \frac{9x}{5} = 136 \Rightarrow 34x = 680 \Rightarrow x = 20$. The first number is $2x = 40$.

Top Questions on Statements and Inferences
- Caroline Hoxby has produced a large body of research looking at college applications by low-income students. In “The Missing One-Offs,” she and Christopher Avery showed that students with high grades and low economic standing often refrain from applying to more prestigious schools, despite those schools’ better financial support. Their research suggests that students who avoid selective schools are usually choosing to apply to the same schools their friends and economic peers do. Hoxby and Avery conclude that this is either a consequence of their being underinformed about their options (a fault of recruitment) or believing that the culture and atmosphere of prestigious colleges wouldn’t be very inviting to them (a fault of the schools and their PR).

The forest officers only have a limited amount of firefighting resources, including helicopters, water trucks, and personnel. They must decide where to allocate these resources to save as much of the park as possible. To maximize their efforts, they prioritise the areas of the park that are home to endangered species and ecosystems that would be the hardest to recover if destroyed by the fire.
Which of the following most mirrors the principle in the passage above?
I. A university offers a limited number of scholarships each year. To ensure the best use of its funds, it prioritizes applicants from underprivileged backgrounds and those with academic potential, believing this will have the most significant long-term impact on the community.
II. A charitable foundation receives an influx of donations for disaster relief. In distributing the funds, it focuses on the hardest-hit communities where homes were completely destroyed, providing them with emergency shelter and rebuilding services before addressing other needs.
III. A large grocery store faces a major food supply shortage due to transportation issues. To minimize the impact on customers, the store decides to limit the sale of high-demand items like milk, bread, and meat, allowing each shopper to purchase only a small amount to ensure everyone can get basic supplies.
