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.

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.

  • b)
    Vipin                 
  • c)
    Harry                                                
  • d)
    Cannot be determined
Correct answer is option 'D'. Can you explain this answer?

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.

If two is subtracted from each odd digit and three is added to each even digit in the number 3675249. How many digits will appear twice in the new number thus formed?

Malavika Rane answered
Understanding the Problem
To solve the problem, we need to transform each digit of the number 3675249 based on whether it is odd or even.
Transformation Rules
- Odd Digits: Subtract 2
- Even Digits: Add 3
Applying the Transformation
Let's break down the number 3675249 digit by digit:
- 3 (odd): 3 - 2 = 1
- 6 (even): 6 + 3 = 9
- 7 (odd): 7 - 2 = 5
- 5 (odd): 5 - 2 = 3
- 2 (even): 2 + 3 = 5
- 4 (even): 4 + 3 = 7
- 9 (odd): 9 - 2 = 7
Now we compile the new digits:
- Original: 3, 6, 7, 5, 2, 4, 9
- Transformed: 1, 9, 5, 3, 5, 7, 7
Counting the Digits
Now let's look at the transformed digits:
- 1
- 9
- 5 (appears twice)
- 3
- 7 (appears twice)
Identifying Digits that Appear Twice
From the transformed digits, we can see that:
- 5 appears twice
- 7 appears twice
Thus, we have two digits that appear twice.
Conclusion
The total number of digits that appear twice in the new number is 2.
Therefore, the correct answer is option 'B'.

Iq Funda answered
According to question,
A's weight is twice as much as of B.
1. A = 2B.
B's weight is four and half times as much as of C.
2. B = 4.5C
C's weight is half times as much as of D.
3. C = D/2.
D's weight is half as much as of E.
4. D = E/2.
E weight is less than A but more than C.
5. A > E > C
from 1 and 2
6. A = 2B = 9C
from 6 and 3
7. A = 2B = 9C = 4.5D
from 7 and 4
8. A = 2B = 9C = 4.5D = 2.25E
so from 8 and 5
A > B > E > D > C
So, E is lighter in weight than A and B.

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

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 there were 69 persons in the row.
Hence, the correct answer is option C.

Prachi ranks sixteenth from the top and fifteenth from the bottom in a certain examination. How many students are there in her class?                
  • a)
    30                                                                     
  • b)
    31                        
  • c)
    32                                                                      
  • d)
    33           
Correct answer is option 'A'. Can you explain this answer?

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.

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.

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".

Correct answer is option 'A'. Can you explain this answer?

Malavika Rane answered
Given information:
- A weight is twice as much as B.
- B weight is four and a half times as much as C.
- C weight is half as much as D.
- D weight is half as much as E.
- E weight is less than A but more than C.

To determine the heaviest article, let's analyze the information step by step.

1. A weight is twice as much as B.
This means that A = 2B.

2. B weight is four and a half times as much as C.
This implies that B = 4.5C.

3. C weight is half as much as D.
This means that C = 0.5D.

4. D weight is half as much as E.
This implies that D = 0.5E.

5. E weight is less than A but more than C.
This means that C < e=""><>

Now, let's combine the equations to find the relationship between the weights of the articles.

Substituting equation 3 into equation 2, we get:
B = 4.5(0.5D) = 2.25D

Substituting equation 2 into equation 1, we get:
A = 2(2.25D) = 4.5D

Substituting equation 4 into equation 3, we get:
C = 0.5(0.5E) = 0.25E

Substituting equation 5 into equations 2 and 4, we get:
0.25E < c="">< e=""><>

Now, let's compare the weights of the articles.

- B = 2.25D
- C = 0.25E
- E <>

From the given information, it is clear that A, B, and E are heavier than C and D. Additionally, A is twice as heavy as B, which means A is the heaviest article. Thus, the answer is option A.

Summary:
- A > B > C > D > E
- A is the heaviest article.

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?
  • a)
    20th
  • b)
    25th
  • c)
    30th
  • d)
    35th
  • e)
    Can’t be determined
Correct answer is option 'D'. Can you explain this answer?

Given Information:
- Roop is 58th from the left end
- 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

Solution:
- Since Roop is 58th from the left end, the number of persons on the right of Roop = 58 - 1 = 57
- According to the given information, the number of persons on the left of Roop = 57
- Gaur sits on the left of Roop, so Gaur is 56th from the left end
- Deep sits exactly in the middle of Roop and Gaur, so Deep is at the 57th position from the left end
- Number of persons between Deep and Roop = 57 - 1 = 56
- According to the given information, the number of persons between Deep and Roop is twice the number of persons on the right of Roop, which is 57
- Therefore, the position of Deep from the right end of the row = Total number of persons - Position of Deep from the left end + 1
- Total number of persons = 58 (Roop's position from the left end) + 57 (Number of persons between Roop and Deep) = 115
- Position of Deep from the right end = 115 - 57 + 1 = 59
Thus, the position of Deep from the right end of the row is 59th, which is not listed in the options provided. Therefore, the correct answer is that it cannot be determined.

In a row of some children facing north, Raju sits 15th from the left and Damu sits 9th from the left. Ramu who sits exactly between Raju and Damu, is 10th from the right. then how many children are there in the row?
  • a)
    18
  • b)
    20
  • c)
    21
  • d)
    23
  • e)
    None of these
Correct answer is option 'C'. Can you explain this answer?

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.

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.

Solution:

Given,

- B is heavier than A and C.
- C is taller than B.
- D is not as tall as C.
- A is shorter than C.
- C is not as heavy as A.
- D is heavier than B but shorter than him.

To find: Who is the heaviest?

Let's analyze the given information step-by-step.

Step 1: B is heavier than A and C.

- B > A
- B > C

Step 2: C is taller than B.

- C > B

Step 3: D is not as tall as C.

- C > D

Step 4: A is shorter than C.

- C > A

Step 5: C is not as heavy as A.

- A > C

Step 6: D is heavier than B but shorter than him.

- D > B
- B > D

From the above information, we can conclude that:

- A < c="">< b=""><>

Therefore, the heaviest person is D.

Hence, the correct answer is option 'C'.

Suresh was born on 4th October 1999. Shashikanth was born 6 days before Suresh. The Independence Day of that year fell on Sunday. Which day was Shashikanth born?

Here , Shashikant was born on 29th September 1999.
∴ 15th August, 1999 was Sunday.
Days upto 29th September from 15 August
( i.e. 16 to 31 August month + 1 to 29 September month ) = 16 days + 29 days = 45 days = 6 weeks 3 old days
∴ Sunday + 3 days = Wednesday.
Hence , Shashikanth born was Wednesday.
