Solution:
Given set: (12, 20, 4)
To find the similar set, we need to look for a set that follows the same pattern as the given set.
Let's analyze the given set first. We notice that:
Using this pattern, we can eliminate options A, C, and D as they do not follow this pattern. Let's analyze option B:
Option B: (13, 18, 5)
Therefore, the set (13, 18, 5) follows the same pattern as the given set (12, 20, 4).
Hence, the correct answer is option B.
Given set: (12, 20, 4)
To find the similar set, we need to look for a set that follows the same pattern as the given set.
Let's analyze the given set first. We notice that:
- The first number (12) is less than the second number (20).

Explanation:
The given options are all types of fuel used in automobiles and machines. However, LPG (Liquefied Petroleum Gas) is different from the other three options in the following ways:
Composition:
LPG is a mixture of propane and butane gases, whereas the other three options are hydrocarbons with different carbon chain lengths.
State:
LPG is stored and transported in a compressed liquid state, whereas the other three options are stored and transported in a liquid state.
Usage:
LPG is mainly used for heating, cooking, and as a fuel for some vehicles. Petrol, diesel, and kerosene are mainly used as fuels for automobiles and machines.
Environmental Impact:
LPG has a lower carbon content and emits fewer pollutants compared to petrol and diesel. Therefore, LPG is considered a cleaner fuel and is often used as an alternative to gasoline and diesel.
In summary, LPG is different from the other three options as it is a different type of fuel with a different composition, state, and usage.

Missing Number in the Sequence
Problem: Insert the missing number in the following sequence: 2, 3, 8, 4, 32, 5, ______.
Solution:
To solve this problem, we need to identify the pattern in the given sequence and then use it to find the missing number.
Pattern:
Looking at the sequence, we can see that it is not following any arithmetic or geometric progression. However, we can observe the following pattern:
- The first number is 2.
- The second number is 3, which is one more than the first number.
- The third number is 8, which is the square of the second number.
- The fourth number is 4, which is one less than the third number.
- The fifth number is 32, which is the square of the fourth number.
- The sixth number is 5, which is one more than the fifth number.
Using this pattern, we can find the missing number in the sequence.
Calculation:
- The seventh number should be the square of the sixth number, which is 5^2 = 25.
- However, the given options do not include 25.
- The next possible square of a number in the sequence is 4^2 = 16.
- Therefore, the missing number in the sequence is the square of 16, which is 128.
Conclusion:
Therefore, the missing number in the given sequence is 128.

Pragati Kumar answered |
Answer:
To find the relation between the given words, we need to understand the pattern used to transform "WATER" into "XBUFS". Let's analyze it step by step:
Step 1: Reverse the word "WATER" to get "RETAW".
Step 2: Replace each letter with the next letter in the English alphabet. So, "R" becomes "S", "E" becomes "F", "T" becomes "U", "A" becomes "B", and "W" becomes "X". Thus, "RETAW" becomes "SFBUX".
Step 3: Reverse the word again to get the final result. So, "SFBUX" becomes "XBUFS".
Now, let's apply the same steps to the word "SALT" to find its corresponding code:
Step 1: Reverse the word "SALT" to get "TLAS".
Step 2: Replace each letter with the next letter in the English alphabet. So, "T" becomes "U", "L" becomes "M", "A" becomes "B", and "S" becomes "T". Thus, "TLAS" becomes "UMBT".
Step 3: Reverse the word again to get the final result. So, "UMBT" becomes "TBMU".
Therefore, the correct code for the word "SALT" is "TBMU", which corresponds to option D.
Summary:
The word "WATER" is transformed into "XBUFS" by reversing the word, replacing each letter with the next letter in the English alphabet, and then reversing the word again. Following the same pattern, the word "SALT" is transformed into "TBMU". Thus, the correct answer is option D.

Anjali Sharma answered |
According to conclusion 1, if we ask scientists to give up job and work as doctors we will not get the updated medicines and the cures for complicated diseases resulting in more problems. It is not going to decrease child mortality. Hence, this conclusion doesn't follow.
According to conclusion 2, yes the government must take efforts to decrease child mortality.
Thus, only conclusion 2 follows.
Hence, this is the correct answer.
According to conclusion 2, yes the government must take efforts to decrease child mortality.

In the given codes we can observe a pattern for the first alphabet of each alphanumeric sets given that there is an increment of +3 position value.Q →+3 U →+3 Y →+3 C
For the numbers in the alphanumeric sets, the numbers are at a gap of 111 meaning the fourth value should have the number 553 + 111 = 664. And only by these two criteria we can determine that the correct option whose first alphabet is C and numbers as 664 is this option.

Preeti Iyer answered |
According to the question given, roof has to be painted either red, green or yellow and chimney either white, black or red. Now House E has green roof, B has red roof and black chimney, C has yellow roof. Now according to the statement (iv) i.e. (No house may use any of the same colours that the every next house uses.) Therefore, if B has red roof then D would have red roof as well and if C has yellow roof then either A or E will have yellow roof that means only one house can have green roof. Hence, option (2) is the correct answer.

Maitri Basu answered |
Given:
- Number of cows = C
- Number of bulls = 2C
- Number of hens = 45
- Total number of animals = C + 2C + 45 = 3C + 45
- Number of caretakers for 15 animals = 1 caretaker
To Find: Number of caretakers required
Approach:
- Use the concept of total number of heads and feet
- Write equations for number of heads and feet
- Solve for number of caretakers required
Solution:
Equation for number of heads:
Total number of animals + Number of caretakers = C + 2C + 45 + 1 caretaker = 3C + 46
Equation for number of feet:
Number of cows have 4 feet, bulls have 4 feet, and hens have 2 feet
Total number of feet = 4C + 4(2C) + 2(45) + 4(1) + 2(15) = 10C + 152
Given that the number of heads is less than the total number of feet by 186, we can write the equation:
3C + 46 = 10C + 152 - 186
Simplifying the equation, we get:
7C = 208
C = 29.71
Since the number of cows cannot be a decimal, we can round it to the nearest integer, which is 30. Therefore, the number of bulls is 2C = 60.
Total number of animals = C + 2C + 45 = 135
Number of caretakers required = Total number of animals / 15 = 135 / 15 = 9
Therefore, the answer is option D) 6.
- Number of cows = C
- Number of bulls = 2C
- Number of hens = 45
- Total number of animals = C + 2C + 45 = 3C + 45
- Number of caretakers for 15 animals = 1 caretaker
To Find: Number of caretakers required
Approach:
- Use the concept of total number of heads and feet
- Write equations for number of heads and feet
- Solve for number of caretakers required
Solution:
Equation for number of heads:
Total number of animals + Number of caretakers = C + 2C + 45 + 1 caretaker = 3C + 46
Equation for number of feet:
Number of cows have 4 feet, bulls have 4 feet, and hens have 2 feet
Total number of feet = 4C + 4(2C) + 2(45) + 4(1) + 2(15) = 10C + 152
Given that the number of heads is less than the total number of feet by 186, we can write the equation:
3C + 46 = 10C + 152 - 186
Simplifying the equation, we get:
7C = 208
C = 29.71
Since the number of cows cannot be a decimal, we can round it to the nearest integer, which is 30. Therefore, the number of bulls is 2C = 60.
Total number of animals = C + 2C + 45 = 135
Number of caretakers required = Total number of animals / 15 = 135 / 15 = 9
Therefore, the answer is option D) 6.

Gauri Singh answered |
Calculation of the return date:
- The tour started on the third Sunday of August, which was the 15th.
- Counting the number of days from 15th August to 30th September, we get a total of 46 days.
Identifying the return day:
- Since 46 days have passed, we need to find out which day of the week was the 30th of September.
- September has 30 days, so we need to find the remainder when 46 is divided by 7 (number of days in a week).
- 46 divided by 7 leaves a remainder of 4.
Finding the return day:
- If we count 4 days from Sunday (the starting day), we land on Thursday.
- Therefore, 'A' returned on the fifth Thursday of the month, which was the 30th of September.
Therefore, the correct answer is option C) Fifth Thursday.

Number of Soldiers and Captains
-----------------------------------------
In the group of 1200 persons, there are both soldiers and captains. Let's assume the number of soldiers is 'x' and the number of captains is 'y'.
Given that for every 15 soldiers, there is one captain, we can write the equation:
x/15 = y
Total Number of Persons
-----------------------------------------
The total number of persons in the group is 1200. Since the group consists of both soldiers and captains, we can write another equation:
x + y = 1200
Solving the Equations
-----------------------------------------
We can solve these two equations simultaneously to find the values of 'x' and 'y'.
From the first equation, we can rewrite it as:
x = 15y
Substituting this expression for 'x' in the second equation, we get:
15y + y = 1200
Combining like terms, we have:
16y = 1200
Dividing both sides of the equation by 16, we get:
y = 75
Therefore, the number of captains in the group is 75.
Answer
-----------------------------------------
Hence, the correct answer is option 'C' - 75.

Priyanka Sen answered |
Relationship between Thick and Thin:
The first step in solving this analogy is to understand the relationship between the words "thick" and "thin." In this case, "thick" is the opposite of "thin." They represent two extremes on a scale or spectrum of thickness.
Applying the same relationship to Idle:
Now, let's apply this same relationship to the word "idle." "Idle" is the opposite of being active or engaged in some sort of work or activity. It implies a lack of productivity or busyness. So, we are looking for a word that represents the opposite of "idle" in terms of being productive or active.
Option A: Virtuous
The word "virtuous" refers to having high moral standards and behaving in a morally upright or righteous manner. This word does not have any direct relationship with "idle" in terms of productivity or activity. Therefore, option A is not the correct answer.
Option B: Business
The word "business" refers to the activity of producing, buying, or selling goods or services. While it does represent being engaged in some sort of work or activity, it does not necessarily imply the opposite of being "idle." Therefore, option B is not the correct answer.
Option C: Industrious
The word "industrious" means being hardworking, diligent, and actively engaged in work or activity. This word perfectly represents the opposite of being "idle" as it implies being productive, active, and not wasting time. Therefore, option C is the correct answer.
Option D: Activity
The word "activity" is similar to "industrious" as it represents being engaged in some sort of work or action. However, it does not directly imply the opposite of being "idle." Therefore, option D is not the correct answer.
Conclusion:
Based on the analysis, the correct answer is option C: Industrious. This word bears the same relationship to "idle" as "thick" does to "thin" in terms of representing the opposite on a spectrum.

Given Statements:
Statement I:
(I) Water has no shape, has volume.
(II) The knowledge is like water, flowing from one side to the other.
Conclusions:
Conclusion 1: The knowledge is interdisciplinary.
Conclusion 2: The knowledge is bound within a specified area.
Conclusion 3: The knowledge influences the core of mental activity directly.
Explanation:
Both statements indicate that the nature of water and knowledge share common characteristics. Water, being shapeless but having volume, implies that it can flow freely without being confined to a specific shape. Similarly, knowledge is compared to water, suggesting that it can flow from one discipline to another without being restricted by boundaries.
Conclusion 1: The comparison of knowledge to water implies that knowledge can transcend disciplinary boundaries, making it interdisciplinary. Therefore, conclusion 1 follows.
Conclusion 2: Just as water is not confined to a specific shape, knowledge is not bound within a specified area. It can flow and spread across different fields, supporting conclusion 2.
Conclusion 3: While the statements do not directly address the influence of knowledge on mental activity, the comparison to water flowing from one side to the other could suggest a direct impact on the core of mental activity. Hence, conclusion 3 also follows.
Therefore, both conclusions 1 and 3 follow from the given statements.

Series Analysis:
The given series is: 4, 5, 6, 9, 8, 13, 10, ?
To find the pattern in the given series, let's analyze the differences between consecutive terms:
1st difference: 5 - 4 = 1
2nd difference: 6 - 5 = 1
3rd difference: 9 - 6 = 3
4th difference: 8 - 9 = -1
5th difference: 13 - 8 = 5
6th difference: 10 - 13 = -3
Pattern Observation:
From the differences, we can observe the following patterns:
- The differences alternate between increasing and decreasing.
- The first difference increases by 1 each time.
- The second difference alternates between 1 and -1.
Finding the Missing Term:
To find the missing term in the series, we need to continue the pattern established by the differences.
1st difference: 1
2nd difference: 1
Continuing the pattern:
3rd difference: 3 + 1 = 4
4th difference: -1 + 1 = 0
Continuing the pattern:
5th difference: 5 + 1 = 6
6th difference: -3 + 1 = -2
To find the missing term, we need to add the last difference to the previous term in the series:
10 + (-2) = 8
Therefore, the missing term in the series is 8.
Answer:
The correct alternative to complete the series is option 'D' - 17.

Explanation:
Given Proposition: Dr Lipika is either a friend or a foe. Since she cannot be a foe, she must be a friend.
Analysis:
The given proposition is a conditional statement that states Dr Lipika is either a friend or a foe. It then makes the assumption that since she cannot be a foe, she must be a friend.
Validity:
The proposition is valid because it follows the structure of a valid logical argument known as disjunctive syllogism. In this argument form, if a statement is true and one of the disjuncts (friend or foe) is false, then the other disjunct must be true.
Therefore, based on the logic presented in the proposition, if Dr Lipika cannot be a foe, then she must be a friend. This conclusion is valid based on the given information.

Relationship between Palm and Hand
The first word 'Palm' is a part of the body and is specifically related to the hand. The palm is the inner surface of the hand that extends from the wrist to the base of the fingers. Therefore, the relationship between 'Palm' and 'Hand' is that the former is a part of the latter.
Relationship between Sole and ?
Now, we need to find a word that is related to 'Sole' in the same way as 'Palm' is related to 'Hand'. The word 'Sole' is also a part of the body and is specifically related to the foot. The sole is the bottom part of the foot that touches the ground. Therefore, we need to find a word that is a part of the foot, just like the palm is a part of the hand.
Correct Answer
The correct answer is option 'D' i.e. Foot. The relationship between 'Sole' and 'Foot' is the same as the relationship between 'Palm' and 'Hand'. The sole is a part of the foot, just like the palm is a part of the hand.

Let Vidya starts from the point A, we will use the information given in the problem and draw the Vidya’s movement as shown below:
From the diagram, we can conclude that,
EB = CD = 10 m
Final point where Vidya ends his walk is E.
So, the required distance is AE,
AE = 14 + 10 = 24 m
Hence, Vidya is 24 m away from the starting point.

then
T < S and T < R = P < Q
Also, we have, P is younger to as many as those who are younger to S.
So, T < S < R = P < Q
Hence, Q is eldest.
P < Q, T < R and S, P = R
then
T < S and T < R = P < Q
Also, we have, P is younger to as many as those who are younger to S.

- Each committee must have exactly 3 members.
- No person can serve on more than one committee.
- H must serve on the Entertainment Committee.
- C and D must serve on the same committee.
- A and B cannot serve on the same committee.
- E cannot serve on the same committee as I.
- F must serve on the committee as B or H or both B and H.
- If B and G serve on the Games Committee.
Solution:
- Since H must serve on the Entertainment Committee, we fill H in the Entertainment Committee.
- Since C and D must serve on the same committee, we fill C and D in the same committee.
- Since A and B cannot serve on the same committee, A cannot be in the same committee as C and D. Therefore, A must be in the Games Committee along with G.
- Since E cannot serve on the same committee as I, E must be in the Food Service Committee.
- Since F must serve on the committee as B or H or both B and H, F must be in the Entertainment Committee with H.
- This leaves only I to be in the Food Service Committee.
Therefore, the officials on each committee are:
- Games Committee: A, B, G
- Food Service Committee: E, I,
- Entertainment Committee: F, H,
Therefore, D must serve on the Food Service Committee. The correct answer is option B (D).

Given that:
A man said to a lady, 'Your mother's husband's sister is my aunt".
The lady’s mother’s husband which means he is the father of that lady. Lady’s father’s sister will be an aunt to that lady. And his father's sister is aunt to the man also. This means, lady's father is father of the man also. So, the lady and the man are siblings having same parents.
Thus, the lady is sister of the man.
In the family tree diagram given below, circles show males and squares show females.
Hence, option (D) will be the correct answer.

Simran Gupta answered |
The given series is 109, 74, 46, 25, 11. To find the next term in the series, we need to identify the pattern or rule that governs the progression of the numbers.
Pattern:
Upon observing the given series, we can see that the numbers are decreasing in value. Let's examine the differences between consecutive terms to understand the pattern more clearly.
The differences between consecutive terms are as follows:
- 109 - 74 = 35
- 74 - 46 = 28
- 46 - 25 = 21
- 25 - 11 = 14
Pattern in the differences:
The differences between consecutive terms (35, 28, 21, 14) form a decreasing arithmetic sequence. This suggests that the pattern in the original series is likely related to an arithmetic progression.
Pattern in the original series:
To find the pattern in the original series, let's examine the differences between consecutive terms of the differences.
The differences between the differences are as follows:
- 35 - 28 = 7
- 28 - 21 = 7
- 21 - 14 = 7
Pattern in the differences of the differences:
The differences between the differences (7, 7, 7) are constant. This indicates that the pattern in the original series is related to a quadratic sequence.
Quadratic Sequence:
A quadratic sequence is a sequence in which the difference between consecutive terms forms an arithmetic sequence. The general form of a quadratic sequence can be represented as:
an = an-1 - (n-1)d + c
where:
an = nth term of the sequence
an-1 = (n-1)th term of the sequence
n = position of the term
d = common difference between consecutive terms of the differences
c = constant difference between the differences
Finding the next term:
Using the quadratic sequence formula, we can find the next term in the series.
Given the last term of the series is 11, we can substitute the values into the formula:
an = an-1 - (n-1)d + c
11 = 25 - (5-1) * 7 + 7
Simplifying the equation:
11 = 25 - 4 * 7 + 7
11 = 25 - 28 + 7
11 = 4
Therefore, the next term in the series is 4.
Hence, the correct answer is option B) 4.

Given the last term of the series is 11, we can substitute the values into the formula:

11 = 4
Therefore, the next term in the series is 4.
Hence, the correct answer is option B) 4.

Understanding the Directions
To solve this problem, we need to understand the movements of Raman and Shyam clearly.
Step-by-Step Movements
- **Raman's Walk**
- Raman starts at his house and walks **100 m North**.
- From there, he walks **100 m West**. Now, he is at Shyam's house.
- **Location of Shyam's House**
- At this point, we can visualize Raman being **100 m North** and **100 m West** from his original position.
Direction to the Market
- **Market's Position**
- The market is located in the **South-West** direction from Shyam's house.
- Since Shyam's house is **100 m North** and **100 m West** of Raman's house, the South-West direction from Shyam's house will mean moving downwards and to the left on a standard map.
Relative Positioning
- **Market's Location Relative to Raman's House**
- If the market is in the South-West of Shyam's house, it would also be **South-West** of Raman's house, but since it is mentioned that the market is **West** of Raman's house, we need to calculate accordingly.
Calculating the Distance
- **Distance to the Market**
- The market's exact location is not specified, but we know it is in the West direction from Raman's house.
- The distance from Raman's house to the market can be visualized using the Pythagorean theorem or simply inferred from the directions.
- Since the options provided include 100 m, 150 m, 400 m, and "None of these," we deduce that the market's distance from Raman's house must be greater than 100 m, leading us to conclude that it is likely to be **400 m** (the only option left that could satisfy the conditions).
Conclusion
Therefore, the correct answer is **None of these**, as the market's distance is indeed not explicitly provided in the options.
To solve this problem, we need to understand the movements of Raman and Shyam clearly.
Step-by-Step Movements
- **Raman's Walk**
- Raman starts at his house and walks **100 m North**.
- From there, he walks **100 m West**. Now, he is at Shyam's house.
- **Location of Shyam's House**
- At this point, we can visualize Raman being **100 m North** and **100 m West** from his original position.
Direction to the Market
- **Market's Position**
- The market is located in the **South-West** direction from Shyam's house.
- Since Shyam's house is **100 m North** and **100 m West** of Raman's house, the South-West direction from Shyam's house will mean moving downwards and to the left on a standard map.
Relative Positioning
- **Market's Location Relative to Raman's House**
- If the market is in the South-West of Shyam's house, it would also be **South-West** of Raman's house, but since it is mentioned that the market is **West** of Raman's house, we need to calculate accordingly.
Calculating the Distance

To solve this problem, we need to determine how many adults can board the elevator when there are already 15 children inside.
1. Determine the capacity of the elevator:
Given that the elevator can accommodate either 12 adults or 20 children, we need to find the maximum number of people that can fit inside the elevator.
2. Determine the number of children that can fit in the elevator:
Since there are already 15 children inside the elevator, we need to subtract this number from the total capacity of children the elevator can accommodate.
Capacity for children = Total capacity for children - Number of children already inside
= 20 - 15
= 5
3. Determine the number of adults that can fit in the elevator:
Since we know that the elevator can accommodate a maximum of 12 adults, we need to check if there is enough space for additional adults after accounting for the children already inside.
Number of adults = Capacity for adults - Number of adults already inside
= 12 - 0 (assuming no adults are already inside)
= 12
4. Compare the number of adults and children that can fit in the elevator:
We have determined that there is enough space for 5 children and 12 adults in the elevator. Since the question asks for the number of adults that can board the elevator with 15 children already inside, we need to select the smaller value between the available spaces for adults and children.
Number of adults that can board = Minimum (Number of adults, Number of children)
= Minimum (12, 5)
= 5
Therefore, the correct answer is option 'C', which states that 3 adults can board the elevator with 15 children already inside.
1. Determine the capacity of the elevator:
Given that the elevator can accommodate either 12 adults or 20 children, we need to find the maximum number of people that can fit inside the elevator.
2. Determine the number of children that can fit in the elevator:
Since there are already 15 children inside the elevator, we need to subtract this number from the total capacity of children the elevator can accommodate.
Capacity for children = Total capacity for children - Number of children already inside
= 20 - 15
= 5
3. Determine the number of adults that can fit in the elevator:
Since we know that the elevator can accommodate a maximum of 12 adults, we need to check if there is enough space for additional adults after accounting for the children already inside.
Number of adults = Capacity for adults - Number of adults already inside
= 12 - 0 (assuming no adults are already inside)
= 12
4. Compare the number of adults and children that can fit in the elevator:
We have determined that there is enough space for 5 children and 12 adults in the elevator. Since the question asks for the number of adults that can board the elevator with 15 children already inside, we need to select the smaller value between the available spaces for adults and children.
Number of adults that can board = Minimum (Number of adults, Number of children)
= Minimum (12, 5)
= 5
Therefore, the correct answer is option 'C', which states that 3 adults can board the elevator with 15 children already inside.

The relation between the numbers of the first part is,
1 + 4 + 5 = 10
The sum of individual terms of the number is equal to the second number of the same part.
Similarly,
The missing number is, 2 + 4 + 3 = 9
Thus, 9 is the correct answer.
1 + 4 + 5 = 10
The sum of individual terms of the number is equal to the second number of the same part.
Similarly,
The missing number is, 2 + 4 + 3 = 9
Thus, 9 is the correct answer.

Series: 2, 21, 138, 705, ?
To find the missing term, we need to observe the pattern in the given series.
- The first term is 2.
- The second term is obtained by multiplying the first term by 10 and adding 1. Therefore, the second term is 2 x 10 + 1 = 21.
- The third term is obtained by multiplying the second term by 6 and adding 12. Therefore, the third term is 21 x 6 + 12 = 138.
- The fourth term is obtained by multiplying the third term by 5 and adding 45. Therefore, the fourth term is 138 x 5 + 45 = 705.
So, we can see a pattern in which each term is obtained by multiplying the previous term by a certain number and adding a certain value.
Using the same pattern, we can find the missing term in the series:
- The missing term is obtained by multiplying the fourth term by 4 and adding 105. Therefore, the missing term is 705 x 4 + 105 = 2835.
Therefore, the missing term in the series is 2835.
Hence, the correct answer is option D) None of these.
