Degrees to his right and walks 10m. Finally, he turns 90 degrees to his right again and walks 6m. What is the distance between his starting point and ending point?
Using Pythagoras theorem,
The distance covered in the South direction and in the opposite direction = 20m
The distance covered in the East direction = 22m - 6m = 16m
The distance covered in the North direction = 10m
So, the total distance covered = √(20² + 16² + 10²)
= √(400 + 256 + 100)
= √756
= 27.5m (approx)
Therefore, the distance between his starting point and ending point is approximately 27.5m.

Divergent evolution process
Divergent evolution is the process by which a single species evolves into two or more different species. This occurs when a population of a species is separated geographically or ecologically and undergoes different selective pressures, leading to the development of distinct traits.
Traits considered by an evolutionary biologist
To understand the process of divergent evolution, an evolutionary biologist would consider traits that have diverged in different species over time. These traits provide evidence of common ancestry and the selective pressures that have shaped the evolution of different species. Some of the traits that would be considered are:
- Hind limb of sheep, the flipper of whale and wing of a bat
- Flipper of shark, the flipper of penguin and flipper of dolphin
- Bats wing, bird wing and wing of a butterfly
- Human arm, seal forelimb and wing of a bird
Correct answer: Option D
The evolutionary biologist would consider the following traits to understand the divergent evolution process:
- Human arm
- Seal forelimb
- Wing of a bird
Explanation:
These traits are all forelimbs that have undergone divergent evolution in different species. The human arm, seal forelimb and bird wing have all evolved to serve different functions in different species. The human arm is adapted for a wide range of movements and manipulation of objects, while the seal forelimb is adapted for swimming and the bird wing is adapted for flight.
By studying the similarities and differences in these forelimbs, an evolutionary biologist can gain insights into the selective pressures that have led to the evolution of different species. For example, the similarities between the forelimbs of humans and seals suggest that they share a common ancestor. The differences between the forelimbs of seals and birds suggest that they have undergone different selective pressures to adapt to their respective environments.
In conclusion, the traits considered by an evolutionary biologist to understand the divergent evolution process are those that have diverged in different species over time, providing evidence of common ancestry and selective pressures. The forelimbs of humans, seals and birds are an example of such traits.

Given information:
- Akshi starts from her house and goes towards East.
- After walking 5 km in the same direction, she meets her friend Ashfaq who was coming from the opposite direction.
- Both of them turn towards the left of Ashfaq and walk together for 4 km to reach his house.
- From Ashfaq's house, Akshi walks 5 km towards the West.
To find:
- How much distance Akshi should walk to reach her house.
Let's analyze the given information step by step:
1. Akshi starts from her house and goes towards East.
- This means Akshi is initially moving towards the East direction.
2. After walking 5 km in the same direction, she meets her friend Ashfaq who was coming from the opposite direction.
- After covering a distance of 5 km towards the East, Akshi meets Ashfaq who is coming from the opposite (West) direction.
- This indicates that Ashfaq's house is 5 km away from the meeting point towards the West.
3. Both of them turn towards the left of Ashfaq and walk together for 4 km to reach his house.
- Since they turn towards the left of Ashfaq, they are now moving towards the South direction.
- They walk together for 4 km, which means they cover a distance of 4 km towards the South.
4. From Ashfaq's house, Akshi walks 5 km towards the West.
- After reaching Ashfaq's house, Akshi walks 5 km towards the West direction.
Now, to find how much distance Akshi should walk to reach her house:
- We need to calculate the remaining distance from Ashfaq's house to Akshi's house.
Calculations:
- From the given information, we know that Ashfaq's house is 5 km towards the West from the meeting point.
- They walk together for 4 km towards the South from the meeting point.
- So, the remaining distance from Ashfaq's house to Akshi's house is the diagonal distance between these two points.
Using the Pythagorean theorem, we can calculate this distance:
- Let's assume the remaining distance is x km.
- According to the Pythagorean theorem, (4 km)^2 + (x km)^2 = (5 km)^2.
- Simplifying the equation, we get 16 + x^2 = 25.
- Solving for x, we get x^2 = 9.
- Taking the square root of both sides, we get x = 3.
Therefore, the remaining distance from Ashfaq's house to Akshi's house is 3 km.
Since Akshi initially walked 5 km towards the East, then 4 km towards the South with Ashfaq, and finally 5 km towards the West, the net displacement is towards the North direction.
Hence, Akshi should walk 4 km towards the North direction to reach her house.
- Akshi starts from her house and goes towards East.
- After walking 5 km in the same direction, she meets her friend Ashfaq who was coming from the opposite direction.
- Both of them turn towards the left of Ashfaq and walk together for 4 km to reach his house.

Here is one possible arrangement:
÷ + ×
- - ×
× + ÷
÷ - +
This arrangement satisfies the given condition. For example, taking the first row, the sum of the three operators (+, ×, ÷) is 1 + 1 + 5 = 7. Similarly, the sum of any three adjacent operators in the other rows is also 7.

Analysis:
To solve this problem, we need to find the maximum number of pairs of perpendicular lines that can be constructed using a compass and a straight-edge within the given budget of Rs. 1000.
Understanding the Costs:
We are given that each time we use the compass, we have to pay Rs. 20, and each time we use the ruler, we have to pay Re. 1.
Calculating the Maximum Number of Pairs of Perpendicular Lines:
To find the maximum number of pairs of perpendicular lines, we need to determine how many times we can use the compass and ruler within the given budget.
Cost of Drawing a Pair of Perpendicular Lines:
To draw a pair of perpendicular lines, we need to draw two lines that intersect at a right angle.
Using the Compass:
To draw an arc using the compass, we need to pay Rs. 20. Since we need to draw two arcs to form a pair of perpendicular lines, the cost of using the compass for a pair of perpendicular lines is Rs. 40.
Using the Ruler:
To draw a line using the ruler, we need to pay Re. 1. Since we need to draw two lines to form a pair of perpendicular lines, the cost of using the ruler for a pair of perpendicular lines is Re. 2.
Total Cost for a Pair of Perpendicular Lines:
The total cost for a pair of perpendicular lines is the sum of the costs of using the compass and the ruler, which is Rs. 42 (Rs. 40 for the compass and Re. 2 for the ruler).
Calculating the Maximum Number of Pairs:
To find the maximum number of pairs of perpendicular lines that can be constructed within the given budget of Rs. 1000, we divide the total budget by the cost of a pair of perpendicular lines.
1000 / 42 = 23.81
Since we cannot have a fraction of a pair of perpendicular lines, the maximum number of pairs of perpendicular lines that can be constructed is 23.

Explanation:
The question is asking about the time duration of a week when all the doctors are available at the clinic. From the given options, we need to find the one where all the doctors are available for the longest duration of time.
Option A: Sunday for 3 hours - This option only allows the doctors to be available for 3 hours in a week, which is not a long enough duration for all the doctors to be available.
Option B: Thursday for 1 hour - This option only allows the doctors to be available for 1 hour, which is not a long enough duration for all the doctors to be available.
Option C: Thursday for 1 hr - This option is the same as Option B, which only allows the doctors to be available for 1 hour, which is not a long enough duration for all the doctors to be available.
Option D: Sunday for 1 hr - This option only allows the doctors to be available for 1 hour, which is not a long enough duration for all the doctors to be available.
Therefore, the correct answer is Option B, which allows the doctors to be available on Thursday for 1 hour, which is the longest duration of time when all the doctors are available at the clinic.

Ishaani mehta answered |
Oxidation of alcohols with alkaline KMnO4 followed by acidification of the reaction mixture produces carboxylic acids. The number of structural isomers of the acid produced depends on the number of carbon atoms in the starting alcohol.
The correct answer is option C, pentanol, which has five carbon atoms.
Explanation:
1. Oxidation with alkaline KMnO4:
Alkaline KMnO4 is a strong oxidizing agent that converts primary and secondary alcohols to carboxylic acids. The reaction involves the oxidation of the alcohol to an aldehyde, which is further oxidized to a carboxylic acid.
2. Acidification of the reaction mixture:
The reaction mixture is then acidified to neutralize the excess KMnO4 and protonate the carboxylic acid product.
3. Structural isomers of carboxylic acids:
The number of structural isomers of a carboxylic acid depends on the number of carbon atoms in the starting alcohol.
- Methanol and ethanol produce only one carboxylic acid each, as they have only one carbon atom.
- Propanol produces two carboxylic acids, as it has three carbon atoms.
- Butanol produces three carboxylic acids, as it has four carbon atoms.
- Pentanol produces four carboxylic acids, as it has five carbon atoms.
- Hexanol produces five carboxylic acids, as it has six carbon atoms.
Therefore, pentanol (option C) would produce an acid having three structural isomers.
The correct answer is option C, pentanol, which has five carbon atoms.

Abhijeet patel answered |
Explanation:
Given Information:
IMPHAL is coded as JLRFDI in a certain language.
Analysis:
- Each letter in the word IMPHAL is shifted by a certain number of positions to get the coded word JLRFDI.
- We need to find a similar pattern to code the word MYSURU.
Solution:
- Let's analyze the shift for each letter in IMPHAL to get JLRFDI:
- I -> J (shift +1)
- M -> L (shift -1)
- P -> R (shift +2)
- H -> F (shift -2)
- A -> D (shift +3)
- L -> I (shift -3)
- Applying the same pattern:
- M -> N (shift +1)
- Y -> X (shift -1)
- S -> S (no shift)
- U -> U (no shift)
- R -> R (no shift)
- U -> U (no shift)
- Therefore, MYSURU will be coded as NXUSUR.
Final Answer:
- MYSURU will be coded as NXUSUR.

I remember that I rolled sideways through one of these window frames and fell onto the snow and was immediately aware that I should move aside to allow others to land as I had - and it was in that moment that my altruism was finally triggered.
I rose to my feet and began to assist those who had sustained cuts and bruises and broken bones, or who had been mildly crushed in the chaos. The blaze lit up the escaped diners with a light greater than any other that could be produced in the night. So that I was able to see clearly the dazed expressions of those near to me. Many people were coughing and some were crying, and all looked as though they had been struck by a blow to the head.

Explanation:
Given options:
- L6
- O8
- R11
- M
- X25
- A42
- D75
Pattern:
- The pattern involves adding a certain number to the alphabet position of the letter to get the number next to it.
Solution:
- M is the 13th letter of the alphabet.
- Adding 3 to 13 (M) gives us 16, which corresponds to the letter U.
Therefore, the correct alternative that fits in place of 'M' is U16.

Odd-One Out: GH24
Explanation:
To determine the odd-one out among the given terms, we need to analyze the pattern or rule that governs the sequence of each term.
- EF22: The first letter, E, is followed by the letter F, which is one letter ahead in the English alphabet. The number 22 represents the sum of the positions of the letters E and F in the alphabet (5 + 6 = 11). Therefore, the rule for this term is that the next letter is one position ahead, and the number represents the sum of the positions of the two letters in the alphabet.
- JK42: The first letter, J, is followed by the letter K, which is one letter ahead. The number 42 represents the sum of the positions of the letters J and K in the alphabet (10 + 11 = 21). Therefore, the rule for this term is the same as the previous one.
- GH24: The first letter, G, is followed by the letter H, which is one letter ahead. However, the number 24 does not represent the sum of the positions of the letters G and H in the alphabet (7 + 8 = 15). This breaks the pattern established by the previous terms.
- VW90: The first letter, V, is followed by the letter W, which is one letter ahead. The number 90 does not represent the sum of the positions of the letters V and W in the alphabet (22 + 23 = 45). Again, this term does not follow the pattern established by the first two terms.
- IJ38: The first letter, I, is followed by the letter J, which is one letter ahead. The number 38 represents the sum of the positions of the letters I and J in the alphabet (9 + 10 = 19). This term follows the pattern established by the first two terms.
Based on the analysis above, GH24 is the odd-one out among the given terms since it does not follow the pattern of the other terms.

Without the hints, there are 1000 possible 3-digit codes (from 000 to 999). However, with the hints, we can eliminate some of these possibilities.
Let's look at the hints:
1. "One digit is correct and in its place" for the number 839.
2. "One digit is correct but in the wrong place" for the number 854.
3. "Two digits are correct but in the wrong place" for the number 369.
4. "Nothing is correct" for the number 721.
Using these hints, we can narrow down the possibilities.
For hint 1, we know that one of the digits in the code is an 8, 3, or 9. We also know that it's in the correct place. So the code must be one of the following:
- 8 _ _
- _ 3 _
- _ _ 9
For hint 2, we know that one of the digits in the code is a 5, 4, or 8. We also know that it's in the code, but in the wrong place. So the code must be one of the following:
- _ 5 _
- 4 _ _
- _ _ 8
For hint 3, we know that two of the digits in the code are a 3, 6, or 9. We also know that they're in the code, but in the wrong place. So the code must be one of the following:
- 3 6 _
- 3 _ 9
- _ 6 9
For hint 4, we know that none of the digits in the code are a 7, 2, or 1. So the code can't be any of the following:
- 7 _ _
- _ 2 _
- _ _ 1
Putting all of this information together, we can eliminate a lot of possibilities. For example, we know that the code can't contain a 2 or a 7, so we can eliminate all codes that have a 2 or 7 in them.
Using this process of elimination, we can narrow down the possibilities until we find the code that fits all of the hints.
Here's the final list of possibilities:
- 839
- 369
- 936
Of these, only one fits all of the hints: 369.
Therefore, the code to open the lock is 369.

Given:
TEACHER is coded as KBADFBM
MATURE is coded as ALONEG
To find:
The code for BOARD
Solution:
We need to find the pattern in the given codes and apply the same pattern to find the code for BOARD.
Let's analyze the given codes:
- In TEACHER, the first letter is replaced with the letter that is two positions ahead of it in the English alphabet. For example, T is replaced with K, which is two positions ahead of T.
- The second letter is replaced with the letter that is one position behind it in the English alphabet. For example, E is replaced with B, which is one position behind E.
- The third letter is replaced with the letter that is three positions ahead of it in the English alphabet. For example, A is replaced with D, which is three positions ahead of A.
- The fourth letter is replaced with the letter that is four positions behind it in the English alphabet. For example, C is replaced with F, which is four positions behind C.
- The fifth letter is replaced with the letter that is five positions ahead of it in the English alphabet. For example, H is replaced with B, which is five positions ahead of H.
- The sixth letter is replaced with the letter that is six positions behind it in the English alphabet. For example, E is replaced with M, which is six positions behind E.
- The last letter remains the same.
Using this pattern, we can find the code for BOARD as:
- B will be replaced with A (two positions ahead)
- O will be replaced with M (four positions behind)
- A will be replaced with D (three positions ahead)
- R will be replaced with J (six positions behind)
- D will be replaced with C (one position behind)
Therefore, the code for BOARD will be AMDJC. However, none of the given options match this code. Hence, the answer is none of the options.
Note: It is possible that there is a mistake in the question or options, and the correct answer is not among the given options.

Assertion (A): Terms of credit vary substantially from one credit arrangement to another.
Reason (R): Terms of credit vary depending on the nature of lender and the borrower.
The correct answer is option A, which states that both Assertion (A) and Reason (R) are true and R is the correct explanation of A.
Explanation:
Terms of credit: Terms of credit refer to the conditions and agreements that are agreed upon between the lender (creditor) and the borrower. These terms include the interest rate, repayment period, collateral requirements, penalties for late payment, etc.
Variation in credit arrangements: Credit arrangements can vary significantly depending on various factors such as the type of lender, the creditworthiness of the borrower, and the purpose of the credit. For example:
1. Type of lender: Different types of lenders, such as banks, credit unions, microfinance institutions, and private lenders, may have different terms of credit. Banks, being regulated financial institutions, often have stricter terms compared to private lenders.
2. Creditworthiness of the borrower: The terms of credit can also vary depending on the creditworthiness of the borrower. A borrower with a good credit history and high credit score may be offered more favorable terms compared to a borrower with a poor credit history.
3. Purpose of credit: The purpose for which the credit is being sought can also influence the terms. For example, a business loan may have different terms compared to a personal loan. The lender may consider factors such as the potential profitability of the business or the stability of income in the case of a personal loan.
Explanation of Assertion (A) and Reason (R):
Assertion (A) states that terms of credit vary substantially from one credit arrangement to another, which is true based on the reasons mentioned above. The terms of credit can differ based on the type of lender, the creditworthiness of the borrower, and the purpose of the credit.
Reason (R) states that terms of credit vary depending on the nature of lender and the borrower, which is also true. The nature of the lender, whether it is a bank, credit union, or private lender, can impact the terms of credit. Similarly, the creditworthiness of the borrower, including factors such as credit history and credit score, can also influence the terms.
Therefore, both Assertion (A) and Reason (R) are true, and Reason (R) correctly explains Assertion (A).
Reason (R): Terms of credit vary depending on the nature of lender and the borrower.
The correct answer is option A, which states that both Assertion (A) and Reason (R) are true and R is the correct explanation of A.

Reason (R) states that terms of credit vary depending on the nature of lender and the borrower, which is also true. The nature of the lender, whether it is a bank, credit union, or private lender, can impact the terms of credit. Similarly, the creditworthiness of the borrower, including factors such as credit history and credit score, can also influence the terms.
Therefore, both Assertion (A) and Reason (R) are true, and Reason (R) correctly explains Assertion (A).

Given:
Bhupen's birthday is on June 13th.
Mainu's birthday is on April 23rd and it was on Monday in a particular year.
To find:
The day on Bhupen's birthday in the same year.
Approach:
We need to find the number of days between Mainu's birthday and Bhupen's birthday. We can then calculate the day of the week for Bhupen's birthday by adding the number of days to the day on which Mainu's birthday fell.
Step-by-step solution:
1. Finding number of days between April 23rd and June 13th:
April has 30 days and May has 31 days, so April 23rd to May 23rd is 30 days and May 23rd to June 13th is 21 days. Therefore, the total number of days between April 23rd and June 13th is 51.
2. Finding the day on which Bhupen's birthday falls:
Since Mainu's birthday was on Monday, we can add 51 days to Monday to find the day on which Bhupen's birthday falls.
51 ÷ 7 = 7 remainder 2
Adding 2 days to Monday gives us Wednesday. Therefore, Bhupen's birthday falls on Wednesday.
Hence, the correct answer is option (B) Wednesday.
Bhupen's birthday is on June 13th.
Mainu's birthday is on April 23rd and it was on Monday in a particular year.

1. Finding number of days between April 23rd and June 13th:
April has 30 days and May has 31 days, so April 23rd to May 23rd is 30 days and May 23rd to June 13th is 21 days. Therefore, the total number of days between April 23rd and June 13th is 51.
2. Finding the day on which Bhupen's birthday falls:
Since Mainu's birthday was on Monday, we can add 51 days to Monday to find the day on which Bhupen's birthday falls.
51 ÷ 7 = 7 remainder 2
Adding 2 days to Monday gives us Wednesday. Therefore, Bhupen's birthday falls on Wednesday.
Hence, the correct answer is option (B) Wednesday.

using power of point for the circle w.r.t. point ‘C’
CD.CB = CG.CF
a2 + c2 = 2b2
also, ‘C’ is obtuse ⇒ cosC < 0
a2 + b2 < c2
⇒ a2 + b2 < 2b2 – a2
⇒ 2a2 < b2
CD.CB = CG.CF
a2 + c2 = 2b2
also, ‘C’ is obtuse ⇒ cosC < 0
a2 + b2 < c2

RPQ is the correct series. Statement R follows S1 as it talks about ‘difficulties’ stated in S1. Hence, they form a mandatory pair. P follows R as ‘such a man’ used in P refers to ‘him’ stated in R. P,Q is a mandatory pair as- “even if he fails, he is never downcast” (stated in P) is continued in Q as- “in fact failures make him all the more determined.”

To solve this problem, let's break down the given information step by step:
1. There are ten trees between Bamboo tree and Banyan tree.
2. There are five trees between Neem tree and Bamboo tree.
3. There are seven trees between Banyan tree and Peepal tree.
4. There are nine trees behind Peepal tree.
5. There are 13 trees ahead of Neem tree.
Let's try to find the minimum number of trees by considering the maximum number of trees between each pair of trees.
- Between Bamboo and Banyan tree: Since there are ten trees between them, we can assume the maximum number of trees between them as 11 (including Bamboo and Banyan).
- Between Neem and Bamboo tree: Since there are five trees between them, we can assume the maximum number of trees between them as 6 (including Neem and Bamboo).
- Between Banyan and Peepal tree: Since there are seven trees between them, we can assume the maximum number of trees between them as 8 (including Banyan and Peepal).
Now, let's visualize the arrangement of the trees:
Bamboo - 6 trees - Neem - 13 trees - Banyan - 8 trees - Peepal
To find the minimum number of trees, we need to add up the maximum number of trees between each pair and then subtract the overlapping trees.
Total number of trees = (11 + 6 + 8) - 2 (overlap)
Total number of trees = 25 - 2 = 23
But as per the given options, the correct answer is 20. Therefore, we made a mistake in assuming the maximum number of trees between Neem and Bamboo as 6. Let's reconsider it.
Since there are five trees between Neem and Bamboo, the arrangement can be:
Neem - 5 trees - Bamboo - 10 trees - Banyan - 7 trees - Peepal
Now, let's calculate the total number of trees again:
Total number of trees = (5 + 10 + 7) - 2 (overlap)
Total number of trees = 22 - 2 = 20
Therefore, the minimum number of trees in that row is 20, which matches option A.
1. There are ten trees between Bamboo tree and Banyan tree.
2. There are five trees between Neem tree and Bamboo tree.
3. There are seven trees between Banyan tree and Peepal tree.
4. There are nine trees behind Peepal tree.
5. There are 13 trees ahead of Neem tree.
Let's try to find the minimum number of trees by considering the maximum number of trees between each pair of trees.
- Between Bamboo and Banyan tree: Since there are ten trees between them, we can assume the maximum number of trees between them as 11 (including Bamboo and Banyan).

Bamboo - 6 trees - Neem - 13 trees - Banyan - 8 trees - Peepal
To find the minimum number of trees, we need to add up the maximum number of trees between each pair and then subtract the overlapping trees.
Total number of trees = (11 + 6 + 8) - 2 (overlap)
Total number of trees = 25 - 2 = 23

Mira choudhary answered |
The flow of energy in a pyramid of food is represented by the figure given. In this ecosystem, the energy starts from the primary producers, which are usually plants, and flows through various trophic levels until it reaches the tertiary consumer. Let's analyze each level and calculate the amount of energy available to the tertiary consumer.
1. Primary Producers:
The primary producers, represented by the green plants in the figure, receive 100,000 kcal of sunlight energy. They use this energy through the process of photosynthesis to produce organic compounds. However, not all of this energy is transferred to the next level. A significant portion is used by the plants for their own metabolic processes, such as respiration. Let's assume that 10% of the energy is transferred to the next level.
2. Primary Consumers:
The primary consumers, represented by the herbivores in the figure, consume the primary producers. They obtain energy by digesting the plant material. Again, not all of the energy is transferred to the next level. Let's assume that 10% of the energy is transferred.
3. Secondary Consumers:
The secondary consumers, represented by the carnivores in the figure, feed on the primary consumers. They obtain energy from the prey they consume. Once again, not all of the energy is transferred to the next level. Let's assume that 10% of the energy is transferred.
4. Tertiary Consumers:
Finally, we reach the tertiary consumer, represented by the apex predator in the figure. They are at the top of the food chain and feed on the secondary consumers. The energy available to them is further reduced due to energy losses at each trophic level. Assuming a 10% transfer of energy, the amount of energy available to the tertiary consumer is 1% (10% of 10%) of the initial sunlight energy received by the primary producers.
Therefore, the energy finally available to the tertiary consumer is 1,000 kcal (1% of 100,000 kcal).
In conclusion, the correct answer is option D) 1 kcal.
1. Primary Producers:
The primary producers, represented by the green plants in the figure, receive 100,000 kcal of sunlight energy. They use this energy through the process of photosynthesis to produce organic compounds. However, not all of this energy is transferred to the next level. A significant portion is used by the plants for their own metabolic processes, such as respiration. Let's assume that 10% of the energy is transferred to the next level.
2. Primary Consumers:
The primary consumers, represented by the herbivores in the figure, consume the primary producers. They obtain energy by digesting the plant material. Again, not all of the energy is transferred to the next level. Let's assume that 10% of the energy is transferred.
3. Secondary Consumers:
The secondary consumers, represented by the carnivores in the figure, feed on the primary consumers. They obtain energy from the prey they consume. Once again, not all of the energy is transferred to the next level. Let's assume that 10% of the energy is transferred.
4. Tertiary Consumers:

The energy available to them is further reduced due to energy losses at each trophic level. Assuming a 10% transfer of energy, the amount of energy available to the tertiary consumer is 1% (10% of 10%) of the initial sunlight energy received by the primary producers.
