Hence, option C is correct.
How many such pairs of letters are there in the word "APPRECIATE" whi...
To find the pairs of letters that have as many letters between them as there are in the English alphabets (both forward and backward), we need to analyze the word "APPRECIATE" and count the number of such pairs.
Step 1: Identify the letters in the word
The word "APPRECIATE" has the following letters: A, P, P, R, E, C, I, A, T, E.
Step 2: Analyze the pairs of letters
We need to look for pairs of letters where the number of letters between them (both forward and backward) is equal to 26, which is the number of letters in the English alphabet.
- Pair 1: A and P
There are 15 letters between A and P (including both forward and backward). This pair does not satisfy the condition.
- Pair 2: A and R
There are 14 letters between A and R (including both forward and backward). This pair does not satisfy the condition.
- Pair 3: A and E
There are 9 letters between A and E (including both forward and backward). This pair does not satisfy the condition.
- Pair 4: A and C
There are 4 letters between A and C (including both forward and backward). This pair does not satisfy the condition.
- Pair 5: A and I
There are 19 letters between A and I (including both forward and backward). This pair does not satisfy the condition.
- Pair 6: A and T
There are 21 letters between A and T (including both forward and backward). This pair does not satisfy the condition.
- Pair 7: A and E
There are 9 letters between A and E (including both forward and backward). This pair does not satisfy the condition.
- Pair 8: P and R
There are 11 letters between P and R (including both forward and backward). This pair does not satisfy the condition.
- Pair 9: P and E
There are 6 letters between P and E (including both forward and backward). This pair does not satisfy the condition.
- Pair 10: P and C
There are 1 letter between P and C (including both forward and backward). This pair satisfies the condition.
- Pair 11: P and I
There are 16 letters between P and I (including both forward and backward). This pair does not satisfy the condition.
- Pair 12: P and T
There are 18 letters between P and T (including both forward and backward). This pair does not satisfy the condition.
- Pair 13: P and E
There are 6 letters between P and E (including both forward and backward). This pair does not satisfy the condition.
- Pair 14: R and E
There are 5 letters between R and E (including both forward and backward). This pair does not satisfy the condition.
- Pair 15: R and C
There are 10 letters between R and C (including both forward and backward). This pair does not satisfy the condition.
- Pair 16: R and I
There are 15 letters between R and I (including both forward and backward). This pair does not satisfy the condition.
- Pair 17: R and T
There are 17 letters between R and T (including both forward and backward). This pair does not satisfy the condition.
