  • d)
    All the given statements are true
  • e)
    E definitely obtained 480 marks
Correct answer is option 'B'. Can you explain this answer?

Shekhinah Reddy answered
Given information:
- A obtained more marks than only two people.
- B obtained more marks than D but not the highest.
- F obtained more marks than only C.
- The one with second highest marks obtained 480 marks.
- The one with second lowest marks obtained 350 marks.

To determine the truth about E's marks, we need to analyze the given information.

Analysis:
- A obtained more marks than only two people. This means A is third from the bottom.
- F obtained more marks than only C. This means F is second from the bottom.
- The one with second highest marks obtained 480 marks. This means the highest marks are more than 480 marks.
- The one with second lowest marks obtained 350 marks. This means the lowest marks are less than 350 marks.

From the above analysis, we can conclude that:
- E obtained more marks than A and F.
- E obtained less marks than the one with second highest marks.
- E obtained more marks than the one with second lowest marks.

Therefore, option B is true as E possibly obtained 500 marks, but we cannot say for sure as we do not have the exact marks of E.

a)14th
b)15th
c)16th 
d)17th
Correct answer is option 'C'. Can you explain this answer?

Sayali kapoor answered
Given:
- Rohan is 7 ranks ahead of Karan in a class of 39.
- Karan's rank is seventeenth from the last.

To find:
- Rohan's rank from the start.

Solution:
- Karan's rank from the start = Total number of students in the class - Karan's rank from the last + 1
- Karan's rank from the last = 17
- Total number of students in the class = 39
- Karan's rank from the start = 39 - 17 + 1 = 23

- Rohan's rank from the start = Karan's rank from the start + 7 (as Rohan is 7 ranks ahead of Karan)
- Rohan's rank from the start = 23 + 7 = 30

Therefore, Rohan's rank from the start is 30.

Answer: (c) 16th.

In a row of boys, A is fifteenth from left and B is fourth from right end there are three boys between A and B. C is first left of A. What is C’s position from right?

    9th
  • b)
    10th
  • c)
    12th
  • d)
    13th
  • e)
    None of these
Correct answer is option 'A'. Can you explain this answer?

Faizan Khan answered
The correct option is A.
Total no of boys = position of A from left + Position of B from right + total boys between A and B.
= 15 + 4 + 3 = 22.
Position of A is 15th from left.
Again, left of A is C -
position of C from left = 15-1 = 14
position of c from right = 22+1 - 14 = 9

    44
  • c)
    60
  • d)
    Can’t be determine
  • e)
    None of these
Correct answer is option 'B'. Can you explain this answer?

Arjun Verma answered
Given information:
- Total number of students = 180
- Number of girls = 2*number of boys
- Ritesh (a boy) is ranked 34th from the top
- There are 18 girls ahead of Rupesh

To find: Number of boys after Rupesh in rank

Solution:
1. Let the number of boys be x. Then, the number of girls will be 2x.
2. Total number of students = x + 2x = 3x
3. Ritesh is ranked 34th from the top. Therefore, there are 33 students ahead of him in rank.
4. Number of girls ahead of Ritesh = 2*33 = 66
5. Number of boys ahead of Ritesh = x - 33
6. Total number of students ahead of Rupesh = 33 + 18 = 51
7. Number of girls ahead of Rupesh = 51 - (x - 33) = 84 - x
8. As per the given information, number of girls = 2*number of boys
Therefore, 2x - (84 - x) = x + 18
3x = 102
x = 34
9. Number of boys after Rupesh = Total number of boys - Number of boys ahead of Rupesh
= 34 - (x - 33)
= 34 - 1
= 33

Therefore, the number of boys after Rupesh in rank is 33, which is option (b).

Explanation:
To determine which child is directly behind the dog, we need to analyze the given information step by step.

Step 1: Initial Position
- Premrajan is ahead of the dog walking down the street.
- Krishnarajan is directly behind the dog.
- Rangarajan is behind Krishnarajan.
- Natrajan is behind Rangarajan.

Step 2: Premrajan joins the pursuit
- As the children and dog pass, Premrajan turns around and joins the pursuit.
- He runs in behind Rangarajan.

Step 3: Krishnarajan runs faster
- Krishnarajan runs faster and is alongside the dog on the left.
- This means that Krishnarajan is no longer directly behind the dog.

Step 4: Rangarajan runs faster
- Rangarajan runs faster and is alongside the dog on the right.
- This means that Rangarajan is no longer directly behind the dog.

Arvind suri answered
Problem: Aruna ranks twelfth in a class of forty-six. What will be her rank from the last?

Solution:

Given, Aruna ranks twelfth in a class of forty-six.

To find: Her rank from the last.

We can find her rank from the last by subtracting her rank from the total number of students and adding 1 to the result.

Formula: Rank from the last = Total number of students – Rank + 1

Applying the above formula, we get,

Rank from the last = 46 – 12 + 1
Rank from the last = 35

Therefore, Aruna’s rank from the last is 35.

Answer: Option (c) 35.

Q. In a row of boys, Jai is eighth from the right and Krish is twelfth from the left. When Jai and Krish interchange positions, Krish becomes twenty first from the left. Which of the following will be Jai’s position from the right? 
a)8th 
b)17th
c)21st 
d)Cannot be determined
Correct answer is option 'B'. Can you explain this answer?

Jatin Unni answered
**Given Information:**
- Jai is eighth from the right.
- Krish is twelfth from the left.
- When Jai and Krish interchange positions, Krish becomes twenty-first from the left.

**To Find:**
- Jai's position from the right after the interchange.

**Solution:**
Let's analyze the given information step by step.

1. Initial Positions:
- Jai is eighth from the right.
- Krish is twelfth from the left.

2. Interchanging Positions:
- When Jai and Krish interchange positions, Krish becomes twenty-first from the left.
- This means that Jai moves to the left and Krish moves to the right.
- Since Krish was initially twelfth from the left and becomes twenty-first from the left, he moves 9 positions to the right.
- Therefore, Jai also moves 9 positions to the left.

3. Finding Jai's New Position:
- Jai was initially eighth from the right.
- After moving 9 positions to the left, Jai's new position from the right will be 8 + 9 = 17.

Therefore, Jai's position from the right after the interchange is 17th.

Hence, option B) 17th is the correct answer.

  • e)
    None of these
Correct answer is option 'B'. Can you explain this answer?

Dia Mehta answered
The correct option is B.
On shifting 4 the left Komal is 10th from the left end of the row. Thus, Komal's original position was 14th from the left end.

Swati is 3 places to the right of Komal's original positions Clearly, swati is 17 th from the left end. Number of girls to the right of swati =(40−17)=23.
 Thus, Swati is 24th from the right end of the row.

Ishan Datta answered
Explanation:

Given information:

- Naveen is taller than Vipin but shorter than Sonu.
- Sonu is taller than Harry but shorter than Amar.

From the given information, we can conclude that:

- Sonu > Naveen > Vipin
- Amar > Sonu > Harry

But we cannot determine who among them is the shortest because we do not have any information about their exact heights or any comparison between Amar and Vipin/Harry. Therefore, the correct answer is option 'D' - Cannot be determined.

In conclusion, even though we have some information about their heights relative to each other, we do not have enough information to determine who among them is the shortest.

  • e)
    Can’t be determined
Correct answer is option 'C'. Can you explain this answer?

Avi Shah answered
Given Information:
- Number of persons on the right of Roop = Number of persons on the left of Gaur
- Gaur sits on the left of Roop
- Deep sits exactly in the middle of Roop and Gaur
- Number of persons between Deep and Roop were twice the number of persons on the right of Roop
- Roop is 58th from the left end

Solution:

Step 1: Find the position of Roop
As Roop is 58th from the left end, the number of persons on the right of Roop = 58 - 1 = 57

Step 2: Find the number of persons on the left of Roop
Since the number of persons on the right of Roop is the same as the number of persons on the left of Gaur, the total number of persons on the left of Roop = 57

Step 3: Find the total number of persons
As Gaur sits on the left of Roop, the total number of persons = Number of persons on the left of Roop + Number of persons on the right of Roop + Roop
Total number of persons = 57 + 57 + 1 = 115

Step 4: Find the position of Deep
Deep sits exactly in the middle of Roop and Gaur, so Deep is at the 57th position from the left end.

Step 5: Find the number of persons between Deep and Roop
Number of persons between Deep and Roop = Twice the number of persons on the right of Roop = 2 * 57 = 114

Step 6: Calculate the number of persons in the row
The total number of persons in the row = Number of persons between Deep and Roop + Deep + Roop
Total number of persons = 114 + 1 + 1 = 116

Therefore, the total number of persons in the row is 116, which is not listed as an option. Since the number of persons in the row cannot be determined from the information given, the correct answer is option e) Can't be determined.

Tushar Das answered
Understanding the Ranks
In a class of 20 students, we need to determine Manav's rank from the bottom given that Alisha's rank is 15th from the top.
Alisha's Rank
- Alisha's rank from the top: 15th
- This means there are 14 students ranked higher than her.
Manav's Rank
- Manav is 4 ranks above Alisha.
- Therefore, Manav's rank from the top can be calculated as follows:
Manav's rank = Alisha's rank - 4
Manav's rank = 15 - 4 = 11th
Calculating Manav's Rank from the Bottom
- Now, to determine Manav's rank from the bottom, we need to consider the total number of students, which is 20.
- The rank from the bottom can be calculated using the formula:
Rank from the bottom = Total students - Rank from the top + 1
Rank from the bottom = 20 - 11 + 1 = 10th
Conclusion
- Thus, Manav's rank from the bottom is 10th.
The correct answer is option D: 10th.

    5 Feet                          
  • d)
    3 Feet
  • e)
    1 Feet
Correct answer is option 'D'. Can you explain this answer?

Diksha menon answered
**Solution:**

Given information:

- P is taller than only three poles.
- S is taller than T but shorter than U.
- U is shorter than P.
- Q is not the tallest.
- The second shortest pole is 2 feet tall.
- The third tallest pole is 5 feet tall.

Possible heights of each pole:

- The tallest pole can be either 6 feet or 7 feet.
- The second tallest pole can be either 5 feet or 6 feet.
- The third tallest pole is 5 feet.
- The fourth tallest pole can be either 4 feet or 7 feet.
- The fifth tallest pole can be either 3 feet or 6 feet.
- The second shortest pole is 2 feet tall.

Possible heights of each pole:

- The tallest pole can be either 6 feet or 7 feet.
- The second tallest pole can be either 5 feet or 6 feet.
- The third tallest pole is 5 feet.
- The fourth tallest pole can be either 4 feet or 7 feet.
- The fifth tallest pole can be either 3 feet or 6 feet.
- The second shortest pole is 2 feet tall.

**Possible heights of pole U:**

- U is shorter than P and P is taller than only three poles. Therefore, U cannot be the tallest or second tallest pole.
- S is taller than T but shorter than U. Therefore, U must be taller than S and T, which means U cannot be the shortest or second shortest pole.
- The second shortest pole is 2 feet tall. Therefore, U cannot be 2 feet tall.
- The third tallest pole is 5 feet tall. Therefore, U cannot be 5 feet tall.
- Q is not the tallest. Therefore, U can be either 3 feet or 7 feet tall.
- However, the fourth tallest pole can be either 4 feet or 7 feet tall. If the fourth tallest pole is 7 feet tall, then U cannot be 7 feet tall. Therefore, U must be 3 feet tall.

Stuti das answered
Given:

Arvind is 8 ranks ahead than Alok in the class.

Alok's rank is 15th from the last.

To find:

Arvind's rank from the start.

Solution:

Let's assume Alok's rank from the start is 'x'.

So, Arvind's rank from the start will be 'x + 8'.

Now, we know that Alok's rank is 15th from the last.

Therefore,

x + 15 = Total number of students in the class

Now, we cannot determine the exact value of 'x' with the given information. We only know that Arvind's rank is 8 ranks ahead of Alok's rank. But we don't know the value of either of their ranks.

Hence, the answer is "Data inadequate".

Conclusion:

The given information is not sufficient to determine Arvind's rank from the start. Therefore, the answer is "Data inadequate".

Nageena is taller than Pushpa but not as tall as Manish. Reena is taller than Namita but not as tall as Pushpa. Who among them is the tallest?
  • a)
    Manish                
  • b)
    Pushpa
  • c)
    Namita               
  • d)
    Nageena
  • e)
    None of these
Correct answer is option 'A'. Can you explain this answer?

Amisha rane answered
Solution:

  • Let's represent the height of each person with their initials. For example, let the height of Manish be M, Pushpa be P, and so on.

  • From the given information, we know that:


    • Nageena is taller than Pushpa (N > P)

    • Manish is taller than Nageena (M > N)

    • Reena is taller than Namita (R > N)

    • Pushpa is taller than Namita (P > N)

    • From the above two statements, we can also infer that Pushpa is taller than Reena (P > R)


  • Putting these statements together, we can create the following height chart:


    • M > N > P > R > N


  • From this chart, we can see that Manish is the tallest among all the given persons, and hence the correct answer is option A.

  • d)
    33           
Correct answer is option 'A'. Can you explain this answer?

Sarika chauhan answered
To find the total number of students in Prachi's class, we need to add the number of students above her in the ranking (from the top) and the number of students below her in the ranking (from the bottom), and then subtract one (to remove the double counting of Prachi herself).

Let's assume that there are 'x' students above Prachi in the ranking and 'y' students below her in the ranking.

From the information given in the question, we know that Prachi ranks 16th from the top and 15th from the bottom. Therefore, we can write two equations based on the given information:

1) x + 15 = y (Prachi is 15th from the bottom)
2) x + y + 1 = total number of students (Adding the number of students above and below Prachi, and subtracting Prachi herself)

To solve these equations, we can substitute the value of y from equation 1 into equation 2:

x + (x + 15) + 1 = total number of students
2x + 16 = total number of students

Now, let's substitute the value of x from equation 1 into this equation:

2(x + 15) + 16 = total number of students
2x + 30 + 16 = total number of students
2x + 46 = total number of students

So, the total number of students in Prachi's class is 2x + 46.

Since we need to find the value of x, let's solve equation 1:

x + 15 = y
x = y - 15

Now, substitute this value of x into the equation for the total number of students:

total number of students = 2(y - 15) + 46
total number of students = 2y - 30 + 46
total number of students = 2y + 16

We know that Prachi ranks 15th from the bottom, so y = 15. Substitute this value into the equation:

total number of students = 2(15) + 16
total number of students = 46

Therefore, there are 46 students in Prachi's class.

However, none of the given options match this answer. So, there might be some error in the question or options provided.

Directions: Study the following information carefully and answer the questions given below.
A certain number of persons were sitting in a row facing north such that number of persons on the right of Roop was same as the number of persons on the left of Gaur. Gaur sits on the left of Roop. Deep sits exactly in the middle of Roop and Gaur, and number of persons between Deep and Roop were twice the number of persons on the right of Roop, who was 58th from the left end.
Q. What is the position of Deep from the right end of the row?

Learnpro Institute answered
Reference: Number of persons on the right of Roop was same as the number of persons on the left of Gaur.
Gaur sits on the left of Roop.
Deep sits exactly in the middle of Roop and Gaur
Inference: Let’s assume that number of persons on the right of Roop and on the on the left of Gaur was X, and the number of persons between Deep and Roop, and Gaur and Deep are Y. Then, Order of persons in the row = X persons + Gaur + Y persons + Deep + Y persons + Roop + X persons
Reference: Number of persons between Deep and Roop were twice the number of persons on the right of Roop, who was 58th from the left end.
Inference: After using the above references, we have: Position of Roop from left end = 58th And, Number of persons between Deep and Roop were twice the number of persons on the right of Roop i.e. 2X = Y.
Here, Number of persons to the left of Roop in the row = X persons + Gaur + Y persons + Deep + Y persons.
Now, 57 = X persons + 1 + 2X persons + 1 + 2X persons X = 11 persons Then,
Order of persons in the row = 11 persons + Gaur + 22 persons + Deep + 22 persons + Roop + 11 persons
Following the final solution we can say that the position of Deep from the right end of the row is 35.
Hence, the correct answer is option D.

Given information:
- Vipul is taller than Kartik.
- Vipul is not as tall as Sam.
- Arvind is taller than Sabha.
- Arvind is shorter than Kartik.

To find: Who is tallest in the group?

Solution:
We can start by arranging the boys in order of their height, based on the given information:

Sam > Vipul > Kartik > Arvind > Sabha

From this order, we can see that Sam is the tallest in the group. Therefore, option (a) Sam is the correct answer.

Explanation:
- Sam is taller than Vipul, who is taller than Kartik. Therefore, Sam is taller than Kartik.
- Arvind is taller than Sabha, but shorter than Kartik. Therefore, Arvind is shorter than Sam and Vipul.
- Thus, Sam is the tallest in the group.

Vira Patel answered



Explanation:



Given Information:

- X got the highest marks in the final exam.
- Y got less than Z.



Analysis:

Since X got the highest marks and Y got less than Z, we can infer the following:

- Y < z="" />< />



Finding the Lowest Marks:

The lowest marks among X, Y, Z, W, and V cannot be determined based on the given information. We only know the relationship between Y, Z, and X, but we have no information about the marks obtained by W and V. Therefore, we cannot determine who got the lowest marks among the five individuals.



Conclusion:

The correct answer is option D: Can't be determined.

Learnpro Institute answered
We have,
Raju sits 15 th from the left and Damu sits 9 th from the left.
Order of persons in the row = 8 persons + Damu + 5 persons + Raju
Also, Ramu who sits exactly between Raju and Damu, is 10 th from the right.
Order of persons in the row = 8 persons + Damu + 2 persons + Ramu + 2 persons + Raju + 6 persons
Total persons in the row = 8 persons + 1 + 2 persons + 1 + 2 persons + 1 + 6 persons
∴ Total persons in the row = 21 persons
Hence, the correct answer is option C.
