Understanding Alphabetical Order
When arranging words in alphabetical order, we look at the first letter of each word. If the first letters are the same, we then compare the second letter, and so on, until we find a difference.
Words to Arrange
- Fault
- Finger
- Floor
- Forget
Step-by-Step Arrangement
1. First Letters Comparison:
- F (Fault)
- F (Finger)
- F (Floor)
- F (Forget)
All words start with the letter "F".
2. Second Letters Comparison:
- a (Fault)
- i (Finger)
- l (Floor)
- o (Forget)
Here, "a" comes first, followed by "i", then "l", and finally "o".
3. Arranging Based on Second Letters:
- Fault (a)
- Finger (i)
- Floor (l)
- Forget (o)
This indicates the order so far:
- Fault
- Finger
- Floor
- Forget
4. Final Arrangement:
- Fault
- Finger
- Floor
- Forget
Identifying the Last Word
In our final arrangement, "Forget" comes last because it has the highest alphabetical value based on the second letters.
Conclusion
Thus, the correct answer is option D: Forget, as it is the last word when all are arranged in alphabetical order.

Understanding the Problem
In the given series, we need to identify the occurrences of the number 8 that are exactly divisible by both the numbers immediately before and after them.
Series Breakdown
The series is:
2, 8, 4, 3, 8, 5, 4, 8, 2, 6, 7, 8, 4, 6, 2, 8, 4, 1, 7
Identifying Relevant 8's
We will analyze each occurrence of the number 8:
- First 8 (2, 8, 4)
- Preceding number: 2
- Succeeding number: 4
- 8 is divisible by 2 (8 ÷ 2 = 4) and by 4 (8 ÷ 4 = 2).
- Valid 8
- Second 8 (3, 8, 5)
- Preceding number: 3
- Succeeding number: 5
- 8 is not divisible by 3 (8 ÷ 3 = 2.67) and not divisible by 5 (8 ÷ 5 = 1.6).
- Invalid 8
- Third 8 (4, 8, 2)
- Preceding number: 4
- Succeeding number: 2
- 8 is divisible by 4 (8 ÷ 4 = 2) and by 2 (8 ÷ 2 = 4).
- Valid 8

- Preceding number: 6
- Succeeding number: 4
- 8 is not divisible by 6 (8 ÷ 6 = 1.33) and by 4 (8 ÷ 4 = 2).
- Invalid 8
- Fifth 8 (2, 8, 4)
- Preceding number: 2
- Succeeding number: 4
- 8 is divisible by 2 and by 4.
- Valid 8
- Sixth 8 (4, 8, 1)
- Preceding number: 4
- Succeeding number: 1
- 8 is divisible by 4 and by 1.
- Valid 8
Conclusion
In total, we have three valid occurrences of 8 that meet the criteria. Therefore, the answer is 3.

Saikat Rane answered |
To solve this problem, we need to analyze the given information step by step.
1. Ashok is 8th from the left end:
This means that there are 7 boys to the left of Ashok.
2. Sanjay is 14th from the right end:
This means that there are 13 boys to the right of Sanjay.
3. There are 12 boys between Ashok and Sanjay:
This means that there are 12 boys between Ashok and Sanjay, including Ashok and Sanjay themselves.
Now, let's calculate the total number of boys in the row.
Total number of boys to the left of Ashok = 7
Total number of boys to the right of Sanjay = 13
Number of boys between Ashok and Sanjay (excluding Ashok and Sanjay) = 12
To find the total number of boys in the row, we need to add these three values together:
Total number of boys = Total number of boys to the left of Ashok + Number of boys between Ashok and Sanjay + Total number of boys to the right of Sanjay
Total number of boys = 7 + 12 + 13
Total number of boys = 32
Therefore, the total number of boys in the row is 32.
Hence, the correct answer is option C) 34.
1. Ashok is 8th from the left end:
This means that there are 7 boys to the left of Ashok.
2. Sanjay is 14th from the right end:
This means that there are 13 boys to the right of Sanjay.
3. There are 12 boys between Ashok and Sanjay:
This means that there are 12 boys between Ashok and Sanjay, including Ashok and Sanjay themselves.
Now, let's calculate the total number of boys in the row.
Total number of boys to the left of Ashok = 7
Total number of boys to the right of Sanjay = 13
Number of boys between Ashok and Sanjay (excluding Ashok and Sanjay) = 12
To find the total number of boys in the row, we need to add these three values together:
Total number of boys = Total number of boys to the left of Ashok + Number of boys between Ashok and Sanjay + Total number of boys to the right of Sanjay
Total number of boys = 7 + 12 + 13
Total number of boys = 32
Therefore, the total number of boys in the row is 32.
Hence, the correct answer is option C) 34.

Explanation:
Given Series:
- H V D K P
Counting the number of letters skipped between adjacent letters:
- H to V: 1 letter skipped (I)
- V to D: 4 letters skipped (W, X, Y, Z)
- D to K: 3 letters skipped (E, F, G)
- K to P: 2 letters skipped (L, M)
Following the rule "Number of letters skipped in between adjacent letters in the series decreases by three":
- We can see that the number of letters skipped between adjacent letters decreases by 3 each time.
Applying the rule to the given options:
a) H V D K P
b) H U E L P
c) H U E L D
d) D M S X A
Correct Answer: Option B - H U E L P
Explanation of the Correct Answer:
- H to U: 1 letter skipped (I)
- U to E: 4 letters skipped (V, W, X, Y)
- E to L: 3 letters skipped (F, G, H)
- L to P: 2 letters skipped (M, N)
Therefore, option B (HUELP) is the series that follows the given rule where the number of letters skipped in between adjacent letters decreases by three.
Given Series:
- H V D K P
Counting the number of letters skipped between adjacent letters:
- H to V: 1 letter skipped (I)
- V to D: 4 letters skipped (W, X, Y, Z)
- D to K: 3 letters skipped (E, F, G)
- K to P: 2 letters skipped (L, M)
Following the rule "Number of letters skipped in between adjacent letters in the series decreases by three":
- We can see that the number of letters skipped between adjacent letters decreases by 3 each time.
Applying the rule to the given options:
a) H V D K P
b) H U E L P
c) H U E L D
d) D M S X A
Correct Answer: Option B - H U E L P
Explanation of the Correct Answer:
- H to U: 1 letter skipped (I)
- U to E: 4 letters skipped (V, W, X, Y)
- E to L: 3 letters skipped (F, G, H)
- L to P: 2 letters skipped (M, N)
Therefore, option B (HUELP) is the series that follows the given rule where the number of letters skipped in between adjacent letters decreases by three.

Rishika Tiwari answered |
Let's analyze each option to determine which letter series has an odd number of letters skipped between adjacent letters.
Option 1: MPRUX
- M to P: 2 letters skipped (N, O) — Even
- P to R: 1 letter skipped (Q) — Odd
- R to U: 2 letters skipped (S, T) — Even
- U to X: 2 letters skipped (V, W) — Even
- This series does not have all odd skips. So, not correct.
Option 2: FIMRX
- F to I: 2 letters skipped (G, H) — Even
- I to M: 3 letters skipped (J, K, L) — Odd
- M to R: 4 letters skipped (N, O, P, Q) — Even
- R to X: 5 letters skipped (S, T, U, V, W) — Odd
- This series has a mix of odd and even skips. So, not correct.
Option 3: EIMQV
- E to I: 3 letters skipped (F, G, H) — Odd
- I to M: 3 letters skipped (J, K, L) — Odd
- M to Q: 3 letters skipped (N, O, P) — Odd
- Q to V: 4 letters skipped (R, S, T, U) — Even
- This series also has a mix of odd and even skips. So, not correct.
Option 4: BDHLR
- B to D: 1 letter skipped (C) — Odd
- D to H: 3 letters skipped (E, F, G) — Odd
- H to L: 3 letters skipped (I, J, K) — Odd
- L to R: 5 letters skipped (M, N, O, P, Q) — Odd
- All skips between letters in this series are odd.
Conclusion:
The correct answer is Option 4: BDHLR, as it is the only series where the number of letters skipped between adjacent letters is consistently odd.

(30 – 24) × 8 = 48
and (23 – 12) × 8 = 88
Therefore, (92 – ?) × 8 = 48
⇒ 92 – ? = 6
⇒ ? = 92 –6 = 86
and (23 – 12) × 8 = 88
Therefore, (92 – ?) × 8 = 48
⇒ 92 – ? = 6
⇒ ? = 92 –6 = 86

Identifying the Consecutive Terms
To find the consecutive terms where the difference is 5, we need to analyze the sequence provided.
Calculating the Differences
1 3 (difference: 2)
3 4 (difference: 1)
4 6 (difference: 2)
6 9 (difference: 3)
9 8 (difference: 1)
8 4 (difference: 4)

Identifying Consecutive Terms with Difference of 5
From the calculations, we can see that there are 4 instances where the difference between two consecutive terms is 5:
- 2 and 7
- 4 and 9
- 3 and 8
- 1 and 6
Therefore, the correct answer is option 'B' - 4 times.

The new letter series obtained on reversing the order of the English alphabet is
Z Y X W V U T S R Q P O N M L K J I H G F E D C B A.
Since the series has an even number of letters there is no such letter which lies exactly in the middle.
