A speciality supermarket sells 320 products. Each of these products was either a cosmetic product or a nutrition product. Each of these products was also either a foreign product or a domestic product. Each of these products had at least one of the two approvals – FDA or EU.

The following facts are also known:



  1. There were equal numbers of domestic and foreign products.

  2. Half of the domestic products were FDA approved cosmetic products.

  3. None of the foreign products had both the approvals, while 60 domestic products had both the approvals.

  4. There were 140 nutrition products, half of them were foreign products.

  5. There were 200 FDA approved products. 70 of them were foreign products and 120 of them were cosmetic products.

A speciality supermarket sells 320 products. Each of these products wa...
(organic or vegan).

Let's define the following variables:

- C = number of cosmetic products
- N = number of nutrition products
- F = number of foreign products
- D = number of domestic products
- O = number of organic products
- V = number of vegan products

From the problem statement, we know that:

- C + N = 320 (since there are 320 products in total)
- C + F = O + F (since each product has at least one of the two approvals)
- N + D = V + D (same reasoning as above)

We can simplify the last two equations to:

- C = O - V
- N = V - F

Now we have three equations and six variables, which means we need to use more information to solve the problem. One possible approach is to use the fact that each variable is non-negative (since we're counting products).

Let's start with O and V. We know that each product has at least one of the two approvals, so:

- O + V - (C + N) >= 0

Substituting C and N from the earlier equations, we get:

- O + V - 320 >= 0
- O + V >= 320

Since O and V are non-negative, their sum must be at least 320.

Next, let's look at F and D. We know that there are no products that are both foreign and domestic, so:

- F + D <= 320="">

Now we can use the equation N = V - F to eliminate F:

- N + D <= 320="" +="" v="">
- N + D - V <= 320="">

Since N, D, and V are non-negative, their sum must be at most 320.

Finally, let's use the equation C = O - V to eliminate V:

- C + N = 320
- C + N - O <= v="">
- (O - V) + N - O <= v="">
- C - O + N <= 0="">

Since C, O, and N are non-negative, their sum must be at least 0.

Putting everything together, we have the following system of inequalities:

- O + V >= 320
- N + D - V <= 320="">
- C - O + N <= 0="">
- C, N, F, D, O, V >= 0

We want to find the maximum possible value of V, since that corresponds to the maximum number of products with the vegan approval. We can rewrite the second inequality as:

- V <= n="" +="" d="" -="" 320="">

Now we can substitute C = O - V and N = V - F to get:

- O - V + V - F = 320 - D
- O - F = 320 - D

This tells us that the difference between the number of organic products and the number of foreign products is equal to the complement of the number of domestic products (i.e., the number of non-domestic products). Since we want to maximize V, we want to minimize F. The smallest possible value of F is 0 (since it's non-negative), which gives us:

- O = 320 - D
- V <= n="" +="" d="" -="" 320="">
- C = O - V =

Read the passage carefully and answer the following questions:Around 2700 years ago, the Greek poet Archilochus wrote: “the fox knows many things; the hedgehog one big thing.” In the 1950s, philosopher Isaiah Berlin used that sentence as the basis of his essay “The Hedgehog and the Fox.” In it, Berlin divides great thinkers into two categories: hedgehogs, who have one perspective on the world, and foxes, who have many different viewpoints. Although Berlin later claimed the essay was not intended to be serious, it has become a foundational part of thinking about the distinction between specialists and generalists.A generalist is a person who is a competent jack of all trades, with lots of divergent useful skills and capabilities. Specialist, on the other hand, is someone with distinct knowledge and skills related to a single area. The generalist and the specialist are on the same continuum; there are degrees of specialization in a subject. There’s a difference between someone who specializes in teaching history and someone who specializes in teaching the history of the American Civil war, for example. Likewise, there is a spectrum for how generalized or specialized a certain skill is. Some skills — like the ability to focus, to read critically, or to make rational decisions — are of universal value. Others are a little more specialized but can be used in many different careers. Examples of these skills would be design, project management, and fluency in a foreign language.Generalists have the advantage of interdisciplinary knowledge, which fosters creativity and a firmer understanding of how the world works. They have a better overall perspective and can generally perform second-order thinking in a wider range of situations than the specialist can. Generalists often possess transferable skills, allowing them to be flexible with their career choices and adapt to a changing world. Managers and leaders are often generalists because they need a comprehensive perspective of their entire organization. And an increasing number of companies are choosing to have a core group of generalists on staff, and hire freelance specialists only when necessary. The métiers at the lowest risk of automation in the future tend to be those which require a diverse, nuanced skill set.When their particular skills are in demand, specialists experience substantial upsides. The scarcity of their expertise means higher salaries, less competition, and more leverage. The downside is that specialists are vulnerable to change. Many specialist jobs are disappearing as technology changes. Stockbrokers, for example, face the possibility of replacement by AI in coming years. That doesn’t mean no one will hold those jobs, but demand will decrease. Many people will need to learn new work skills, and starting over in a new field will put them back decades. That’s a serious knock, both psychologically and financially.What’s the safest option, the middle ground? By many accounts, it’s being a specialist in one area, while retaining a few general iterative skills-a generalizing specialist. Many great thinkers are (or wer e) generalizing specialists. Shakespeare, Da Vinci, Kepler, and Boyd excelled by branching out from their core competencies. These men knew how to learn fast, picking up the key ideas and then returning to their specialties. Unlike their forgotten peers, they didn’t continue studying one area past the point of diminishing returns; they got back to work — and the results were extraordinary.Q.Which of the following statements CANNOT be inferred from the passage?
