The original pair of words "Illiterate : Uneducated" shows a relationship where one word describes a lack or absence of the other word. Similarly, the pair "Vision : Sight" also exhibits the same relationship, where the word "Vision" describes the ability to see or have sight.

If we interchange the positions of the first and second letters of all the words, we need to ensure that the resulting arrangement forms meaningful English words. However, in this case, none of the words will form meaningful English words regardless of the interchange. Therefore, the answer is None.

The series follows a pattern where each letter is repeated in alphabetical order, and then the letters are reversed and repeated in the reverse alphabetical order. The first letter 'a' is repeated, then the next letter 'z' is added, followed by 'a' and 'b' in alphabetical order. Then the pattern repeats with 'y' added, followed by 'a', 'b', and 'c' in alphabetical order. The next letter in the pattern would be 'e', as it follows the same pattern of adding the next letter in alphabetical order.

If all the letters in each of the words are arranged alphabetically within the word, only one word will remain unchanged. This means that the letters in this word are already in alphabetical order, so rearranging them alphabetically will not change the word itself.

The sentence "The Independence Day was celebrated by the residents" is the correct answer because it correctly changes the sentence from active voice to passive voice. It maintains the same meaning as the original sentence, but the focus is shifted from the residents to the Independence Day itself, making it a passive construction.

The series is based on the English alphabetical order. The first letter in each term is moving backward by 1 position, and the second letter is moving forward by 1 position. Therefore, in the missing term, the first letter should be L (one position backward from M) and the second letter should be I (one position forward from H). Hence, the missing term is "LI". However, none of the given options match this pattern. Therefore, the correct answer cannot be determined and the question is incomplete.

The word "put off" is the most effective word to fill in the blank because it means to postpone or delay something. In the given sentence, the speaker is saying that even if it rains all day, they will not be able to delay or postpone their journey.

The watch is going slow by 30 seconds per hour. From 8am to 8pm, there are 12 hours. So, the watch will be behind by 12 * 30 seconds, which is 360 seconds or 6 minutes. Therefore, the actual time at 8pm will be 8pm - 6 minutes, which is 7.54.

F is related to H as a daughter-in-law because a daughter-in-law is the wife of one's son.

Sanjay invested Rs 16,000 for two years and received Rs 17,640 on maturity. To find the rate of interest per annum, we can use the formula for compound interest: A = P(1 + r/n)^(nt), where A is the final amount, P is the principal amount, r is the rate of interest, n is the number of times interest is compounded per year, and t is the time in years. Plugging in the given values, we have 17,640 = 16,000(1 + r/100)^(2*1). Solving this equation, we find that r is approximately 5%. Therefore, the rate of interest per annum is 5%.

The missing dollar is a result of a mathematical error in the calculation. The total cost of the room is $25, which was paid by the three guests. The additional $5 given to the bellboy and distributed among the guests does not affect the total cost of the room. Therefore, there is no missing dollar.

The word "occult" refers to something that is mysterious or secret, often associated with supernatural or mystical practices. The word "mysterious" also conveys a similar meaning, suggesting something that is difficult to understand or explain. Therefore, "mysterious" is the most nearly similar word to "occult" among the given choices.

The dealer bought the dry fruits in the ratio of 12:15:20 by weight. Let's assume he bought 12 kg of dry fruits at Rs 100 per kg, 15 kg at Rs 80 per kg, and 20 kg at Rs 60 per kg.

He sold the first two quantities at a 20% profit, which means he sold them at Rs 120 per kg and Rs 96 per kg respectively.

To have no gain or loss in selling the whole quantity, the selling price for the third quantity should be equal to the cost price.

Let's assume the selling price for the third quantity is x.

So, (12*120) + (15*96) + (20*x) = (12*100) + (15*80) + (20*60)

Simplifying the equation, we get 1440 + 1440 + 20x = 1200 + 1200 + 1200

Combining like terms, we get 40x = 600

Dividing both sides by 40, we get x = 15

Therefore, the selling price for the third quantity is Rs 15 per kg, which means there is a loss of Rs 45 per kg.

To find the percentage loss, we divide the loss by the cost price and multiply by 100.

Percentage loss = (45/60) * 100 = 75%

Therefore, the dealer suffered a 75% loss for the third quantity.

Since none of the options provided match the calculated loss percentage, the correct answer cannot be determined.

The correct answer is "He is known to me" because it is the passive voice form of the sentence "I know him". In the passive voice, the subject of the sentence receives the action, which in this case is "him" being known by "me".

To find the width of the ground, we need to know either the length or the perimeter of the ground. Statement II provides the perimeter of the ground, which is 396 mts. However, statement I does not provide any information about the length or the width of the ground. Therefore, using statement II alone, we cannot determine the width of the ground. Hence, the answer is C, as both statements are needed to find the width of the ground.

To find the amount of flour worth Rs 25 per kg that must be blended with the 30 kgs of flour worth Rs 30 per kg, we can use the concept of weighted average. Let x be the amount of flour worth Rs 25 per kg. The total cost of the blended variety is (30 * 30) + (x * 25). The total weight of the blended variety is 30 + x. To have a gain of 10%, the selling price per kg should be 1.1 times the cost price per kg. So, we have the equation (1.1 * 30) = ((30 * 30) + (x * 25))/(30 + x). Solving this equation, we get x = 36 kg. Therefore, 36 kgs of flour worth Rs 25 per kg must be blended with 30 kgs of flour worth Rs 30 per kg.

The boat takes 19 hours to travel downstream from point A to point B and back to point C, which is midway between A and B. This means that the time taken to travel from A to C is half of the total time, which is 19/2 = 9.5 hours. The speed of the boat in still water is given as 14 km/h and the velocity of the stream is 4 km/h. To find the distance between A and B, we can use the formula: distance = speed × time. The speed of the boat relative to the stream is the difference between the speed of the boat in still water and the velocity of the stream, which is 14 - 4 = 10 km/h. Therefore, the distance between A and B is 10 × 9.5 = 95 km. Since the boat travels from A to B and back, the total distance is 2 times the distance between A and B, which is 2 × 95 = 190 km. However, this is the total distance traveled by the boat, so the actual distance between A and B is half of this, which is 190/2 = 95 km. Therefore, the correct answer is 180 km.

The passage suggests that the author believes it is important to remain calm and composed even during challenging times. This implies that the author advocates for maintaining a level-headed approach and not letting difficult circumstances overwhelm or affect one's composure. The phrase "we must keep cool even in difficult times" aligns with this idea and is consistent with the author's opinion.

The error in the sentence is in part B. The word "were" should be replaced with "was" to maintain subject-verb agreement. Since "the number" is a singular noun, it should be followed by a singular verb form.

The correct answer is "Language : Conversation" because both pairs consist of a broader term (money, language) and a specific action or use related to that term (transaction, conversation). In both cases, the second word represents a common activity or purpose associated with the first word.

The correct answer is B. The verb "was" should be changed to "were" to agree with the plural subject "The Cabinet Ministers and the Prime Minister." The correct sentence should be "The Cabinet Ministers and the Prime Minister were at the airport."

The passage suggests that we should avoid keeping hectic schedules because they can harm our body. This implies that involving ourselves too much in work and not taking breaks can have negative consequences on our health. Therefore, it is important to prioritize self-care and avoid overworking ourselves.

When a boat is moving upstream, it has to work against the current, which reduces its effective speed. The total speed of the boat is the sum of its speed in still water and the speed of the current. In this case, the total speed of the boat is 4 km/h + 2 km/h = 6 km/h. If the boat takes 9 hours to travel a certain distance upstream, we can calculate the distance using the formula distance = speed × time. Therefore, distance = 6 km/h × 9 hours = 54 km.
When the boat is moving downstream, it benefits from the current, which increases its effective speed. The total speed of the boat is now 4 km/h - 2 km/h = 2 km/h. We can calculate the time it will take to travel the same distance downstream using the formula time = distance / speed. Therefore, time = 54 km / 2 km/h = 27 hours. However, since we are looking for the time in hours, we convert 27 hours to 3 hours.

C is related to E as a father.

Let's assume that pipe B takes x hours to fill the reservoir alone. Since pipe A can fill the reservoir 5 hours faster than B, it will take x - 5 hours for A to fill the reservoir alone.

If both pipes A and B work together, they can fill the reservoir in 6 hours. This means that in 1 hour, they can fill 1/6th of the reservoir.

In 1 hour, pipe A can fill 1/(x-5)th of the reservoir, and pipe B can fill 1/xth of the reservoir.

So, we have the equation 1/(x-5) + 1/x = 1/6.

Solving this equation, we find that x = 10.

Therefore, pipe A can fill the reservoir alone in 10 hours.

The relationship between "Sailor : Pirate" is that a sailor is someone who works on a ship, and a pirate is someone who commits acts of robbery and violence at sea. Similarly, the relationship between "Police : Robbers" is that police are law enforcement officers who catch and apprehend criminals, and robbers are individuals who commit theft and other illegal activities. Both pairs involve one group of individuals who are responsible for preventing or stopping illegal activities, and another group who engage in those illegal activities.

The motorboat travels 10 km upstream and 10 km downstream in 55 minutes. Since the stream is running at a speed of 2 km/h, the effective speed of the motorboat against the current is (10 - 2) = 8 km/h. Similarly, the effective speed of the motorboat with the current is (10 + 2) = 12 km/h. The total time taken for the round trip is 55 minutes, which is equal to 55/60 = 11/12 hours. Using the formula distance = speed × time, we can set up the equation (8 × 11/12) + (12 × 11/12) = 20 × t, where t is the speed of the motorboat in still water. Solving this equation, we get t = 22 km/h.

The man takes twice as long to row up the river compared to rowing down the river. This suggests that he is rowing against the current while rowing up and with the current while rowing down. Let's assume the speed of the current is x km/h. When rowing up, the effective speed of the man is (4.5 - x) km/h, and when rowing down, the effective speed is (4.5 + x) km/h. Since the time taken to row up is twice the time taken to row down, we can set up the equation: (4.5 - x) * 2 = (4.5 + x). Solving this equation, we find x = 1.5 km/h, which is the speed of the stream.

The given code language follows a pattern where the letters in the word are rearranged in reverse order. Applying this pattern to the word 'PLANK', we get 'KNALP'. Therefore, the correct answer is AKLNP.

The error is in part B of the sentence. The correct phrase should be "suit him" instead of "suits him" to maintain subject-verb agreement.

The correct answer is A. The statement "x is not equal to 0" implies that x cannot be 0. Therefore, if x is the reciprocal of y, it means that y cannot be 0 either. Since both x and y cannot be 0, it is possible for their sum to be 0. Additionally, the statement "x is not equal to 1" does not provide any information about the sum of x and y. Therefore, statement I is necessary to determine if x + y = 0.

Let's assume there are x inlet pipes and y outlet pipes.

Each inlet pipe can fill the tank in 9 hours, so the rate at which each inlet pipe fills the tank is 1/9.
Each outlet pipe can empty the tank in 6 hours, so the rate at which each outlet pipe empties the tank is 1/6.

When all the pipes are opened, the net rate at which the tank is being filled is the sum of the rates of the inlet pipes minus the sum of the rates of the outlet pipes.

Therefore, the equation can be written as:
x/9 - y/6 = 1/9

Given that the tank is filled in 9 hours, we can substitute x = 6 in the equation:
6/9 - y/6 = 1/9

Simplifying the equation, we get:
2/3 - y/6 = 1/9

Cross multiplying and solving for y, we get:
y = 4

Therefore, there are 4 inlet pipes.

The given sentence is grammatically correct. The error is in part C where "are" should be replaced with "is" to maintain subject-verb agreement. The correct sentence would be "A series of lectures of Indian philosophy is arranged by the University."

In the word NEUTRAL, there are three such pairs of letters that have the same number of letters between them in the word as they have between them in the English alphabetical series. These pairs are "E" and "T" (2 letters between them in both the word and the alphabet), "A" and "L" (3 letters between them in both the word and the alphabet), and "U" and "R" (4 letters between them in both the word and the alphabet). Therefore, the correct answer is Three.

The error in the sentence is in part C. The correct sentence should be "he will resume in two days" instead of "he will resume after two days." The use of "after" implies that he will resume his duties after two days have passed, whereas the correct usage is "in" which indicates that he will resume his duties two days from now.

The word "autonomy" refers to the ability to act independently and make decisions without being controlled by others. On the other hand, "slavery" represents the complete opposite, as it involves being owned and controlled by someone else. Therefore, "slavery" is the most nearly opposite word to "autonomy" among the given choices.

The mother of G is F because the question states that F is the mother of either B or F. Since G is not an option for being F's child, the only possibility is that G is F's child.

The correct answer is Monalisa : English. In the original pair, Utopia is a place that represents an ideal society and English is the language associated with it. Similarly, Monalisa is a famous painting and English is the language associated with it.

The word "to" is the most effective word to fill in the blank to make the sentence meaningfully complete. It is commonly used in the phrase "there is an exception to every rule" to indicate that the exception applies or relates to the rule.

The relationship between "overlook" and "aberration" is that "overlook" means to fail to notice or consider something, and "aberration" means a departure from what is normal or expected. Similarly, the relationship between "condone" and "offence" is that "condone" means to accept or allow behavior that is morally wrong or offensive, and "offence" refers to behavior that is morally wrong or offensive. Therefore, "condone : offence" has the same relationship as "overlook : aberration".

From statement (I), we can deduce that each boy has an equal number of sisters and brothers. This means that there must be an odd number of children in the family, as each boy would have at least one sister. From statement (II), we can deduce that each girl has twice as many brothers as sisters. This means that each girl must have at least two brothers. Combining both statements, we can conclude that there are at least three boys and three girls in the family, making a total of at least six children. Therefore, the family must have at least seven children. Hence, the answer is D.

The number can be found by subtracting the two preceding numbers from 30. In this case, 10 + 11 = 21, and 30 - 21 = 9. Therefore, the number is 9.

The correct answer is B. Both statements (I) and (II) provide enough information to determine whether x>y. Statement (I) can be rearranged to x/y = 6/8 = 3/4, which means x is less than y. Statement (II) shows that x is equal to y + 4, which means x is greater than y. Therefore, the answer is B.

The word "to" is the most effective word to fill in the blank because it indicates the purpose or intention of helping oneself. It suggests that one should take whatever they can use without wasting it.

The volume of a cubical box can be calculated by finding the cube of the length of one side.
Statement (I) provides the area of one face, which is not sufficient to determine the length of one side and therefore the volume.
Statement (II) provides the length of the longest diagonal, which is also not sufficient to determine the length of one side and therefore the volume.
Combining both statements, we still do not have enough information to determine the length of one side and therefore the volume. Therefore, the answer is D, as the information provided is not sufficient.

Based on the given information, we know that Rony is taller than Joy and John is shorter than Rony. Since there is no information given about the height comparison between John and Joy, we cannot determine who is taller between the two. Therefore, the correct answer is "Impossible to tell whether John or Joy is taller."
