    48
  • b)
    51
  • c)
    52
  • d)
    55 ​
  • e)
    None of these
Correct answer is option 'B'. Can you explain this answer?

Shraddha Chopra answered
Solution:

Let the total number of students in the class be 'x'.

Ram ranks 12 from the top, which means there are 11 students above Ram in the class.

Ram also ranks 40 from the bottom, which means there are (x - 40) students below Ram in the class.

Therefore, the total number of students in the class can be found by adding the number of students above Ram, the number of students below Ram, and Ram himself.

x = (11 + 1 + x - 40)

Simplifying the above equation, we get:

x = 52

Therefore, there are 52 students in the class.

Hence, the answer is option (c) 52.

Akanksha Patel answered
Problem: Anil is fourteenth from the left end and 7 from the right end. How many boys must be added to the line such that there are 30 boys in the line?

Solution:
Let the total number of boys in the line be 'x'.
According to the given question, Anil is 14th from the left end and 7th from the right end.

Therefore, the number of boys to the left of Anil = 14 - 1 = 13
The number of boys to the right of Anil = 7 - 1 = 6

Hence, the total number of boys in the line = number of boys to the left of Anil + number of boys to the right of Anil + Anil
x = 13 + 6 + 1
x = 20

So, we have a total of 20 boys in the line. We need to add more boys to make it 30.

Number of boys to be added = 30 - 20 = 10

Therefore, we need to add 10 more boys to make the total number of boys in the line 30.

Answer: The correct option is (b) 10.

Six people A, B, C, D, E and F obtained different marks in an exam. 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.

Q.
Which ofthe following is true with respect to E as per the given information?
  • a)
    E obtained less marks than only two people
  • b)
    E possibily obtained 500 marks
  • c)
    E obtained more marks than D but less than B
  • 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.

In a classof 180, where girls are twice the number of boys. Ritesh a boy ranked thirty fourth from the top. If there are eighteen girls ahead of Rupesh how many boys are after him in rank?

    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).

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

so suresh from left=17th
so remaining from right side-23 students
so from right side suresh is 24th.
option is "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.

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.

Palak Sharma answered
Solution:

Naveen is counting down from 32 and Mano is counting upwards the numbers starting from 1 and calling out only the even numbers. They will call out at the same time when they reach a common number. Let's find out what that common number is.

Counting down from 32:

32, 31, 30, 29, 28, 27, 26, 25, 24, 23, 22, 21, 20, 19, 18, 17, 16, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1

Counting upwards from 1 (only even numbers):

2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 96, 98, 100

Finding the common number:

To find the common number, we need to look for the even numbers in the counting down list that match the even numbers in the counting upwards list. The even numbers in the counting down list are:

32, 30, 28, 26, 24, 22, 20, 18, 16, 14, 12, 10, 8, 6, 4, 2

Out of these, only 22 is present in the counting upwards list. Therefore, the common number they will call out at the same time is 22.

Answer: (a) 22.

    38
  • d)
    39 ​
  • e)
    None of these
Correct answer is option 'B'. Can you explain this answer?

Simran Choudhury answered
Given, a particular student is 19th from both the ends. Let us assume the total number of students in the class to be x.

From the left end, the position of the particular student is 19th.

From the right end, the position of the same student is also 19th.

Thus, the number of students between the two ends = (19-1) + (19-1) = 36.

Hence, the total number of students in the class = Number of students between the two ends + the particular student + number of students to the left of the particular student + number of students to the right of the particular student

x = 36 + 1 + (19-1) + (19-1)

x = 37

Therefore, the number of students in the class is 37, which is option (B).

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.

Naveen is taller than Vipin but shorter than Sonu. Sonu is taller than Harry but shorter than Amar. Who among them is the shortest with regard to height?
  • a)
    Naveen                                                   
  • 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.

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

Nandini Rane answered
Solution:

Given: Atul is 10 from the right in a line of boys and 7 from the left.

To find: How many boys should be added to the line such that there are 30 boys in the line?

Let the total number of boys in the line be x.

According to the given information, we can form the equation:

x = 10 + 7 - 1
x = 16

Therefore, there are 16 boys in the line.

To make the total number of boys in the line to be 30, we need to add:

30 - 16 = 14 boys

Therefore, the answer is (c) 14.

Hence, option (c) is the correct answer.

Rutuja Gupta answered
Solution:

Given,
Sumit is 16th from the right end and Maya is 18th from the left end.

To find:
The number of people between Sumit and Maya.

Approach:
We need to find the total number of children in the row and then subtract the position of Sumit from the right end and the position of Maya from the left end to get the number of children between them.

Calculation:
Total number of children in the row = 16 + 18 - 1 = 33 - 1 = 32

Number of children between Sumit and Maya = 32 - 16 - 18 = 6

Therefore, the answer is option (c) 6.

Debolina Pillai answered
's position from the left end of the row?

To solve this problem, we need to visualize the positions of each person in the row. We can start by drawing a diagram:

1 2 3 4 5 6 7 8 9 10 11 12 ... Ranbir ... 42

From the information given, we know that Ranbir is sitting 12th from the right end, so we can count 12 people from the right to find his position:

1 2 3 4 5 6 7 8 9 10 11 12 ... Ranbir ... 42

Next, we know that Hritik is sitting 5th to the right of Ranbir, so we can count 5 people to the right of Ranbir to find Hritik's position:

1 2 3 4 5 6 7 8 9 10 11 12 ... Ranbir ... Hritik ... 42

We also know that Deepika is sitting 21st to the left of Hritik, so we can count 21 people to the left of Hritik to find Deepika's position:

1 2 3 4 5 6 7 8 9 10 11 12 ... Ranbir ... Hritik ... 22 23 ... Deepika ... 42

Finally, we know that Shahid is 7th to the right of Deepika, so we can count 7 people to the right of Deepika to find Shahid's position:

1 2 3 4 5 6 7 8 9 10 11 12 ... Ranbir ... Hritik ... 22 23 ... Deepika ... 29 30 31 32 33 34 35 ... Shahid ... 42

Therefore, Shahid is sitting in the 35th position from the left end of the row.

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.

Learnpro Institute answered
Reference:
Ankit is taller than Nitin and Kapil.
Nitin is taller than Kapil.
Inference:
After using the above hints, we have:
Order of Height:
Ankit > Nitin > Kapil
Reference:
Dinesh is shorter than only Sumit.
Inference:
After using the above hints, we have:
Order of Height:
Sumit > Dinesh > Ankit > Nitin > Kapil
Following the final solution, we can say that if the height of Nitin is 154 cm then the height of Kapil can be 150 cm.
Hence, the correct answer is option A.

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.

A group of dancers are standing in a line for their performance. Joseph tried to calculate his rank from either side and found that his rank is 19th. Find the total number of dancers standing in that line.
  • a)
    36
  • b)
    37
  • c)
    38
  • d)
    39
Correct answer is option 'B'. Can you explain this answer?

Ritika Choudhury answered
Ans: b
Explanation: If we count till Joseph from the left side, then he will be 19 dancers. Similarly, from the right-hand side, the total number of students to Joseph will also be 19. Now adding both and subtracting 1 (dual occurrence of Joseph) we will get = 19 + 19 - 1 = 37.
