    , FDA (Food and Drug Administration) approval or CE (Conformité Européene) approval.

    Let's represent the four categories of products as follows:

    C = Cosmetic products
    N = Nutrition products
    F = Foreign products
    D = Domestic products

    We know that:

    - The total number of products is 320, so C + N = 320.
    - Each product is either a cosmetic or a nutrition product, so C + N = 320 is a complete partition of the set of 320 products.
    - Each product is either a foreign or a domestic product, so F + D = 320 is also a complete partition of the set of 320 products.
    - Each product has at least one of the two approvals, FDA or CE, so we can represent this as the union of the two sets:
    FDA ∪ CE = C + N + F + D = 320

    We want to find out how many products have both FDA and CE approvals.

    We can start by applying the inclusion-exclusion principle:

    |FDA ∪ CE| = |FDA| + |CE| - |FDA ∩ CE|

    We don't know |FDA| or |CE|, but we do know that every product has at least one of the two approvals, so:

    |FDA ∪ CE| = 320

    We also know that each product has at least one approval, so:

    |FDA ∩ CE| ≥ 0

    Putting it all together, we get:

    320 = |FDA| + |CE| - |FDA ∩ CE|
    |FDA ∩ CE| ≤ |FDA|, and ≤ |CE|
    |FDA ∩ CE| ≥ 0

    We want to find |FDA ∩ CE|, so we need to find a way to express |FDA| and |CE| in terms of the information we have. We can do this by using the fact that every product has at least one approval.

    Let's define:

    FC = Products that are foreign and have FDA approval
    NC = Products that are domestic and have FDA approval
    FE = Products that are foreign and have CE approval
    NE = Products that are domestic and have CE approval

    We know that every product has at least one approval, so:

    C = FC ∪ NC ∪ FE ∪ NE
    F = FC ∪ FE
    D = NC ∪ NE

    We can use these relationships to express |FDA| and |CE| in terms of FC, NC, FE, and NE:

    |FDA| = |FC| + |NC|
    |CE| = |FE| + |NE|

    Now we can use the inclusion-exclusion principle to find |FDA ∩ CE|:

    320 = |FDA| + |CE| - |FDA ∩ CE|
    320 = |FC| + |NC| + |FE| + |NE| - |FDA ∩ CE|

    We don't know |FDA ∩ CE|, but we can find an upper bound for it using the fact that each product has at least one approval:

    |FDA ∩ CE| ≤ min(|FDA|, |CE|) = min(|FC| + |NC|, |FE| + |NE|)

    We can also find a lower bound for |FDA ∩ CE| using the fact that each product has at least one approval:

    |FDA ∩ CE| ≥ max(0, 320 - |FC| -

    Similar CAT Doubts

    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?
