Statement 1:All chickens are birds.Statement 2:Some chickens are hens....

Statements I and II can be represented as venn diagrams in the following ways:

As ‘Female birds lay eggs’, so ‘All birds lay eggs’ is incorrect.

Conclusion ‘Hens are Birds’ may or may not be true as can be seen from the Venn diagrams.

Conclusion ‘Some chickens are not hens’ is also not definitely true as can be seen from the third Venn diagram.

Hence, option (d).

Statement 1:All chickens are birds.Statement 2:Some chickens are hens....

Analysis:

Statement 1: All chickens are birds.
- This statement establishes the relationship between chickens and birds.

Statement 2: Some chickens are hens.
- This statement implies that there are chickens that are specifically female (hens).

Statement 3: Female birds lay eggs.
- This statement highlights a characteristic of female birds.

Conclusion:
- While the given statements provide information about the relationship between chickens, hens, and birds, they do not provide enough information to conclusively determine the truth of the following statements.

Options:

I. All birds lay eggs.
- This statement cannot be inferred from the given information, as it only mentions female birds laying eggs.

II. Hens are birds.
- This statement can be inferred from the given information, as hens are specified as a type of chicken, and chickens are stated to be birds.

III. Some chickens are not hens.
- This statement cannot be definitively determined from the given information, as it is possible that all chickens mentioned are hens.
Therefore, the correct answer is option 'D' - None of the statements can be confirmed as known facts based on the given information.

Directions: Study the following information and answer the given question.In a commercial complex of five storeys, five different offices are there viz. HCL, IBM, Infosys, Nugent and Accenture on the floors I, II, III, IV and V, respectively. There are total 6000 employees working in the building. Each employee is employed in only one of the companies. Out of the total employees in the building, 18% are working in IBM and 37% are working in HCL. The ratio of the employees working in Accenture to that working in Infosys is 17 : 19. Only 9% of the total employees are working in Nugent. The ratio of male employees to that of female employees working in Nugent is 7 : 2 and that in Infosys is 17 : 21. The number of male employees working in Accenture is five times the number of female employees. The number of male employees working in HCL is 480 less than the number of male employees working in Accenture. Out of its total employees, IBM has employed approximately 44.45% females.Q.If after some time, 30% of the employees of Infosys in the building have switched their job to Nugent in the same building, out of which approximately 30% were male employees, then what will be the new ratio of the male employees to the female employees in Nugent after switching jobs?

Direction: Read the following passage carefully and answer the questions given below:The world’s largest Northern gannet colony at the Bass Rock, an island off the coast of North Berwick, Scotland has been recently decimated by avian influenza (H5N1) or bird flu. H5N1 has caused unprecedented loss of tens of thousands of birds in the U.K. The annual congregations on breeding grounds quickly turned into a superspreader event as highly pathogenic H5N1 ripped through bird colonies, leaving many lying dead on the beaches or remote islands. The impact of this disease is very serious for bird conservationists. Recently, intra-mammal transmission of H5N1 in captivity in mink farms was recorded, posing a bigger concern in relation to zoonotic potential. In India, the latest major avian flu outbreak in 2020-2021 swept through many States causing mass mortality of wild birds which brought the concerns on the lack of active surveillance to the forefront, and how wetland and waterfowl habitats at the interface of poultry need to be monitored.While the avian flu outbreaks coincide with the peak migratory season leading to post outbreak surveillance and culling, there are also reports of outbreaks in the off-season suggesting endemic transmission within the poultry sector. India is the fastest growing egg producer in the world, but unlike in Europe, poultry birds here are not vaccinated against flu. Furthermore, the farms with a diversity of animals or in the vicinity of nearby wetlands increases the potential for the viruses to undergo reassortment that can potentially generate more virulent strains — H5N1 or H7N9 — which could then infect humans. Despite this potential, there is no active surveillance in the poultry sector. There may be no efficient human-to-human transmission mechanism yet, however, the risk cannot be ruled out as the virus continues to evolve. We need an active and passive year around surveillance network under One Health which connects monitoring of human and animals in a shared environment.Waste water-based Epidemiology or pathogen surveillance has become an integral component of environmental surveillance providing near real-time information on health and community exposure to pathogens. While environmental surveillance is not a new concept and has been used widely for monitoring several pathogens, it offers an excellent tool. Birds infected with avian influenza virus shed large quantities of virus in their faeces, saliva and nasal secretions for about a week. Currently, virus surveillance is reactive and relies on sampling dead birds. Environmental surveillance would be a great non-invasive tool that can be done without disturbing the birds and can be used to obtain both host and viral genetic material. Most importantly, environmental surveillance should be complemented with effective carcass collection and testing, and better biosecurity on poultry farms to improve preparedness and response in the future.Q.From the given argument, which conclusion can be drawn?

Out of this, 35% male employees from HCL and 120 female employees from Accenture leave their jobs. Remaining employees, who leave the job, are from IBM only. What will be the ratio of the male employees to the female employees in IBM who have left their job?
