All questions of Analogy and Classification for Class 3 Exam

Option c is correct

Understanding the Analogy
The analogy presented in the question is based on the relationship between two forms of media.
Radio and Music
- Radio is a medium that primarily delivers music.
- It serves as a platform through which people experience and enjoy music.
Television and Movies
- Similarly, television is a medium that showcases movies.
- It acts as a platform for viewing and enjoying films.
Why Option A is Correct
- Both pairs share a common theme: they represent a medium and the content delivered through that medium.
- Just as radio is to music, television is to movies, making 'Movie' the correct answer.
Analysis of Other Options
- Temperature: This relates to a measurement, not a form of media or content.
- Height: This also refers to a physical measurement and does not relate to television.
- Weight: Like height and temperature, weight is another measurement and has no connection to the television medium.
Conclusion
In conclusion, the correct answer is option 'A' (Movie) because both radio and television serve as platforms for specific types of content, with radio providing music and television offering movies. The other options do not fit this relationship, as they do not represent media or content.

D is correct

Explanation:

In this analogy, we are given a ratio of 9 to 27. We need to find the missing term in the analogy, which is equivalent to the ratio of 27 to the missing term.

To solve this analogy, we need to find a number that has the same relationship to 27 as 9 has to 27.

Step 1: Find the common factor between 9 and 27.
- The common factor between 9 and 27 is 9.

Step 2: Divide each term by the common factor.
- 9 ÷ 9 = 1
- 27 ÷ 9 = 3

Step 3: Write the ratio in simplified form.
- The simplified ratio is 1 : 3.

Step 4: Apply the same ratio to the missing term, which is 27, to find the answer.
- 27 ÷ 3 = 9

Therefore, the missing term in the analogy 9 : 27 :: 27 : ? is 9.

Explanation:

The given analogy is ABC : DEF :: GHI : ?

To solve this analogy, we need to identify the relationship between the first pair of terms (ABC and DEF) and apply the same relationship to the second pair of terms (GHI) to find the missing term.

Relationship between ABC and DEF:
In the given pair, each letter in the first term (ABC) is replaced by the letter that comes after it in the alphabetical order to form the second term (DEF).

A becomes D, B becomes E, and C becomes F.

Applying the same relationship to GHI:
Based on the relationship identified in the first pair, we need to find the letters that come after G, H, and I in the alphabetical order.

G becomes J, H becomes K, and I becomes L.

Therefore, the missing term that completes the analogy is JKL.

Answer: The missing term in the analogy GHI : ? is JKL (option C).

Understanding the Pattern
To solve the analogy presented, we need to identify the relationship between the letters and the numbers.
Letter Sequence Analysis
- The first sequence of letters is: A, C, E, G
- These letters are in alphabetical order and skip one letter each time:
- A (1), C (3), E (5), G (7)
Number Sequence Analysis
- The corresponding numbers for these letters are: 1, 3, 5, 7
- These numbers are also in a sequence, increasing by 2:
- 1, 3, 5, 7
Identifying the Next Set
- Now, we analyze the second set of letters: B, D, F, H
- Following the same pattern:
- B (2), D (4), F (6), H (8)
- Notice that each letter corresponds to an even number, just like the first set corresponds to odd numbers.
Conclusion
- If B corresponds to 2, D to 4, F to 6, and H to 8, the next number in the sequence (following the pattern of adding 2) would be:
- 2, 4, 6, 8
Thus, the correct answer is option 'B', which completes the pattern of even numbers corresponding to the letters in the second series.

School : Teacher

In a hospital, the primary person responsible for providing medical care to patients is a doctor. Similarly, in a school, the primary person responsible for providing education to students is a teacher. Therefore, the correct answer is option B) Teacher.

Explanation:

1. Hospital and Doctor:
- In a hospital, doctors are the medical professionals who diagnose and treat illnesses, injuries, and diseases.
- They are highly trained and have specialized knowledge in their field.
- Doctors examine patients, order diagnostic tests, prescribe medications, and perform surgeries when necessary.
- They play a crucial role in providing medical care and ensuring the well-being of patients.

2. School and Teacher:
- In a school, teachers are the professionals responsible for imparting knowledge and educating students.
- They create lesson plans, deliver lectures, facilitate discussions, and assess students' understanding through assignments and exams.
- Teachers play a vital role in shaping the minds of students, fostering their intellectual growth, and helping them acquire necessary skills.

3. Similarities between Hospital and School:
- Both hospitals and schools are institutions that serve specific purposes in society.
- Hospitals focus on providing medical care, while schools focus on providing education.
- In both settings, professionals are assigned specific roles to fulfill the institution's objectives.

4. Doctor and Teacher:
- Just as doctors are essential in hospitals, teachers are essential in schools.
- Both doctors and teachers require specialized knowledge and skills in their respective fields.
- Both professions involve working closely with individuals (patients or students) to meet their specific needs.
- Doctors and teachers both contribute to improving the well-being and development of individuals they serve.

Conclusion:
The relationship between a hospital and a doctor is parallel to the relationship between a school and a teacher. Just as a doctor is the key figure in a hospital, a teacher is the primary figure in a school. Therefore, the correct answer to the given analogy is option B) Teacher.

Tiger : Meat :: Cow : Grass

Explanation:

The relationship between the words "Tiger" and "Meat" is that a tiger eats meat. Similarly, we need to find the relationship between the words "Cow" and another word.

Tigers eat Meat
- Tigers are carnivores, which means they eat meat.
- Their diet consists mainly of other animals, such as deer, wild boar, and water buffalo.
- Tigers need the nutrients and energy provided by meat to survive and thrive.

Cows eat Grass
- Cows are herbivores, which means they eat plants.
- Their diet consists mainly of grass, hay, and other plant-based materials.
- Cows have a unique digestive system that allows them to extract nutrients from plant fibers.

Conclusion:
Just like tigers need meat to survive, cows need grass to survive. Therefore, the correct answer is option B: Grass.

Problem Analysis:
The given problem is an analogy problem where we need to find a number that is related to the first pair of numbers in the same way as the second pair of numbers are related to each other.

Given Pair:
The given pair is 5 : 25. To find the relationship between these two numbers, we can divide 25 by 5, which gives us 5.

Applying the Relationship:
Now, we can apply the same relationship to the second pair of numbers, which is 7 : ?. If we divide the second number by the first number, we get 7. Therefore, the missing number is 7.

Answer:
The missing number in the analogy is 7.

Therefore, the correct answer is option D) 49.

Introduction:
In this analogy question, we are given a relationship between a plant and a tree. We need to identify a similar relationship between two other options, specifically between a puppy and one of the given options: tiger, cow, dog, or cat.

Explanation:
To solve this analogy, we need to understand the relationship between a plant and a tree. A tree is a type of plant. Similarly, we need to find an option where a puppy belongs to that category.

Analysis of Options:
Let's analyze each option to find the best fit for the analogy:

a) Tiger: A tiger is a completely different category from a puppy. Tigers belong to the category of big cats, whereas puppies belong to the category of dogs. So, option A is not the correct answer.

b) Cow: A cow is again a different category from a puppy. Cows belong to the category of animals, specifically mammals, whereas puppies belong to the category of dogs. So, option B is not the correct answer.

c) Dog: A dog is the correct answer. Puppies belong to the category of dogs. Just like a tree is a type of plant, a puppy is a type of dog. So, option C is the correct answer.

d) Cat: A cat is again a different category from a puppy. Cats belong to the category of animals, specifically felines, whereas puppies belong to the category of dogs. So, option D is not the correct answer.

Conclusion:
Based on the analysis, we can conclude that the correct answer is option C, Dog. Just like a tree is a type of plant, a puppy is a type of dog.

Explanation:
To find the missing set of 3 alphabets in the given series, let's analyze the pattern in the given series:

The first element of each set is the alphabet at position 1, 2, 3, respectively, in the English alphabet sequence.
- ACE: A is at position 1, C is at position 3, and E is at position 5.
- BDF: B is at position 2, D is at position 4, and F is at position 6.

So, we can infer that the third element of each set is the alphabet at position 5, 6, 7, respectively, in the English alphabet sequence.

Now, let's find the missing set of 3 alphabets from the given choices:

a) DEI: D is at position 4, E is at position 5, and I is at position 9.
- This does not follow the pattern observed in the given series.

b) DIG: D is at position 4, I is at position 9, and G is at position 7.
- This does not follow the pattern observed in the given series.

c) DFH: D is at position 4, F is at position 6, and H is at position 8.
- This does not follow the pattern observed in the given series.

d) EGH: E is at position 5, G is at position 7, and H is at position 8.
- This follows the pattern observed in the given series.

Therefore, the missing set of 3 alphabets in the given series is EGH, which corresponds to option 'd'.
